history: I used to be very trusting but my friends and family used it to hurt me all the time. Now I don't trust anyone anymore. I am more careful with people. I was so naive and trusting in the past and people took advantage of me a lot. I'm a lot more careful now.
current: you'll need to be careful around me then. I'm the type of person who takes advantage of people
next: I am careful around everybody. But I appreciate the warning.
