Confession time:

My younger sister has 4 kids... the oldest is mine. ;)

Our parents diorced when I was 12, she went with Dad and I had to stay with mom.  They moved several states away.

The first summer I went to visit him, she and I started fooling around... it continued later visits.  Now we are both adults, living in different states, but we still fool around whenever we can, and no one else knows. :-P  And, we have a daughter together.... she is 13 now.  No one knows this, my daughter thinks I am just her uncle.  According to her facebook profile she looks like a natural flirt, and if she is anything like her mom she is already fooling around with boys. ;)

So... there you go! :-P
