What do you do when you have a trusting nature but you've been burned before but you soooooo wanna trust again?

Well it depends, if you are talking about someone that burned your trust before... I'd be extra wary and well wouldn't really trust again. I mean people are just what they are. For good or bad.
And with new people... that's different, you can take your time to know them, and well if you feel like you want to trust in them do it. They may surprise you being trustworthy people... or not. The only way to know it is finding out...
