@therealpaul,
Respect the way you think! Yes, it can happen to anyone! But very few of people try to help them truly! A big social problem you have discussed in a great way! Be a homeless man... yeah I won't think about it :/ And yeah I don't know the pain of them :/ But I wish we can do something!
Really appreciate your effort and thank you very much for sharing with us!

Cheers~
