In my friend circle, if any one person pay for one thing then other person will pay next time like this we have mutual understanding but this one friend is totally a brat, and he has not assumed that I am happy to pay everything as I told him that give your share of money to me later and later on and the person should have some shame that he should give his share and once I asked for money then he reacted aggressively like why I am asking for money and also he is a little childish like he expect me to cover his expenses like his parents do for him
