How often do adults make friends?

I don't think that's something any one person can answer; too many variables.

Do you ever experience "bullying" in the workplace?

No, but then I don't work, am bonkers, and I stand my ground.

In what ways have you been "bullied" before? Why? Was it out of jealousy?

Was bullied a lot at school, usual reasons: was tall, had glasses, actually tried to learn, was clearly smarter than them, actually had a personality, was quirky, and so on. Jealousy? Meh, I doubt it.

What brought this on?
