Thanks hankster & nichole!
The father of the son had stated to me, "You are too sensitive. You think poorly of my son. Your thinking is a bit perverse.". To which I responded "My background or psych issues have nothing to do with my thoughts on this. CSA DOES occur withing blood related families, so being "close familial friends" has nothing to do with it. Etc.". The following day I was ALWAYS around the little girl.

Nothing was going to happen to her whether her Mother likes me or not.
