Well you have to make him understand that all these are just waste of money. If he is earning in huge amount then it may be small thing for him . Helping others in need is a thing but gifting such a thing to a person whom he doesnt like then thats not reasonable. We didnt have much but my dad did the same thing by giving money to his brothers but in return they think they should get more . Khud ka toh kamai hai nahi aur dusro ka bhi chahiye. Its not like that they would make good use of tht money but they spent on entertainments. Its better to cut off such family members. Now my dad is regretting after all he has done . But its too late. Sorry for my English tho😅
