Ex-con vs non-con

Is the ex-con more suspicious than the non-con?

Do the fathers who were dirty devils back in the day give new boyfriends the worst interrogations?

I think so.

Because they were there. They lived that naughty life. They know the capacity for sneakiness.

Now whether they can keep a lid on their suspicions and interrogations is the real question.

Can they leave enough room to build trust first before coming down on others like a ton of bricks?
