I understand your point but dear the best thing you can do for them is making them responsible for themselves and not providing for them.
I have someone like that much older than me,doesnt even have a bank accout.
I wanted to build him,i started by telling him to create a bank account and i will be sending 5k monthly because he uses friends account to receive money.
He insisted that i send through peoples account,omo i locked up,nothing for him, ignored his mesaage. He is a relative
My plan was from that bank account,i will be giving him challenges to help him build himself then give a monthly reward,he failed from the start.
Its not like you are hiding your source of income or that they are handicapped,stop giving them.
The next time they ask, send them the link to steemit.com to create an account and make introduction or add them to airdrop group,if you dont take hard option,you might feed them all your life
