Sadly, he probably does sleep with his own kids, even if it's innocently right now because they are so young (not the usual 10 or 12). Plus, one of his children is a girl. It's good the cops stepped in now, imagine (sarcasm) how lonely and left out she would feel in a few years.
What? Give money away without getting anything (the attention of the kids and the sleepovers - ew, creepy) in return???? Never.
Eeewwww, must go wash, not clean enough...
That's the bottom line, your so right. He is getting something out of this, it's not for the kids. If it was, then he would be doing all this "stuff for the kids " routine anonymously, withought all this attention from them.
