Have you ever lost money by giving loan to someone?

number of times !

yes...and i have learned. i was trusting and trusted a lot of people, thinking they would pay me back...$400 to an old friend...who thinks its rude that i tracked him down to ask for my money back...$500 to my husband friend who needed it to pay rent...who moved without telling us and never paid us back....i leaned my lesson, and i don't loan out money anymore...because i'm not going to see any come back. i've borrowed a lot, but i've already returned it when i could.
