['I use to be very trusting until 8 years ago.']
Why 8 years? That's a very specific time ago.
I was at a company picnic with co-workers. I walked away from the picnic to another area of the park with 3 co-workers I felt trusting with and even felt they were friends. The 3 guys ended up attacking me and leaving me for dead. I'm not so trusting now.
