you're daughter's amazing xD

...You were never curious as to why Kate was never in any yearbook photos, around the neighborhood, or asking to come over your house? YDI for being an oblivious asshole.

YDI, YDI, YDI. Like others have said, it is YOUR JOB as a parent to meet your daughter's friend and her parents before you let her stay overnight at their house. And now you're letting your young daughter hang out with her "boyfriend" at his house without meeting the guy or his parents? He could be "Kate"'s brother and be way older for all you know. Seriously, take better care of your daughter. It is every parent's job to know who their kid's friends are, and what they do when they're together. Otherwise, you won't know how to help them if they get into trouble. I can't say it enough. YDI.

It wasn't just "a" sleepover, it was MULTIPLE sleepovers. And if your daughter is 12/13 (depending on time frame)... YDI for not caring about your kid enough, clearly.

look on the bright side, she has probably been going out with him for 2 years, so u know she's "not around".

Clearly the "sleep overs" have knocked some stupid inside of her, since she thinks you wouldn't notice Kate and her boyfriend lived in the same house.

You let her sleep over some girl's house for 2 years and never met her? Wow

*****!!!

Even if Kate is a real person you've seen before (which from the way you word it I'd say she's not which is even worse), if you didn't notice Kate wasn't there after two years you're a very irresponsible parent. You can't trust your kids these days, let's just be realistic. If your kid wants to go sleepover at a friend's house you walk in the door with them the first time and leave after you actually see "Kate" or whoever else it is. Not thinking to do that the first time I could understand, but if you don't even see the person after a month or two you're just a fool if you don't get at least a little suspicious.

how have u not met Kate??
