DEAR Taiwo,

Please, help me, although, thisdoes not directly involve me, but I am deeply concerned and irritated by what is going on. My elder sister, who happens to be the oldest of us all  is behaving like a kid and all attempts by us all; her younger siblings to make her see through the young man she is dating is not working out.
I am sorry to say this, but I wouldn't know if age makes one to lose his/her senses. My sister is 48, she is the first child of the family while I am in the second to the last child.
Though, she hasn't been lucky when it comes to the affairs of the heart and men's issues, but she is a success in her business and with this she has been able to support our mother who is our only surviving parent to train us in school.
I have just completed my National Youth Service Corps exersice (NYSC), and I moved in with her in Lagos so she could help me secure a job through her contacts. She was away from home when I got there and I wasn't expecting to see anybody in her house. I was however shocked to meet a young man seated on the couch drinking from a big bottle of Baileys Irish Crème as early as 10 in the morning.
I greeted him and went into the visitor's room. I was actually irritated by this. He didn't know who I was and I was able to listen to some of his telephone conversations. Two of his friends also visited and I overheard some of their discussions.
I didn't realise they were talking and making jest of my sister until she came back from work and introduced him to me as her boyfriend. This young man couldn't be older than me, I am 26. For one, my sister expected me to respect him while he disrespects my sister and make jest of her behind her back.
After my sister introduced us to each other, I didn't mince words to ask if he and his friends have been talking and calling my sister names. He denied this and even denied that he had visitors while my sister was at work.
I wanted to argue with him, but my sister cautioned me. I didn't spare him when my sister went into the kitchen and I told him point blank that I won't stand by and watch him destroy my sister.
The following morning after my sister left for work, he tried to be friendly with me, but sincerely, I cannot stand his guts, so I told him off. I could not help but put a call across to my mother to let her know what was going on.
I later learnt that he is a university drop out and he has been wasting my sister's money on his overseas travels where he wants to go and start school again. Through his conversation with his friends, I learnt that my sister has tried several times to set him up in business, but he ends up squandering the money and he would come back for more. His friends call my sister moneybag among other derogatory names.
I tried telling my sister this, but she is of the opinion that I am doing this because I do not like her boyfriend. The last straw, however, came last week, when I returned from a job interview and the dayguard informed me that my sister's live-in-lover had a woman in the house and according to him; the woman is the guy's sugar mummy who always visited him.
The guard said he couldn't tell my sister because he knows she really loved him. He advised me to go in quietly so I could catch them in the act.
Sincerely, I did catch them in the act. After eating and drinking my sister's wine, both of them were  naked having sex in my sister's living room with music blaring in the afternoon when many people are busy making money.
They were both shocked to see me and when they got over this, the woman had the guts to challenge me and even asked him who I was. I walked out of the living room because I didn't want to commit murder. I didn't know what he told her, but after she left, he came pleading that I shouldn't tell my sister.
I told him off and dared him to stop me. The point is that if I do, will she believe me? I can't stand this guy and they both know. My sister however does not know the reason for my renewed hostility. One thing is clear, I can't leave my sister's house for him. Should I tell my sister all I know?
Hadiza.
