I think it is safe to assume that one of the most horrifying, awkward moments that can be encountered as a parent is having your kids walk in on you while doing the hanky-panky. It's a fact of life that we all have sex, but no matter how mature I try to be about the situation, I still feel mortified whenever I think about it and bury my head in my hands as I let out an embarrassed shriek. (Or I pull a face akin to Luke's. Feel free to leave a caption for this picture in the comments, because this one is worth at least a thousand words.)
Of course, as fate would have it, it happened to us recently. Yes, Luke walked in on us while we were having sex. Luckily he is still just a little guy and didn't see anything specific, but he is definitely old enough to recognize that something a little different was going on. I am also happy to report that I did not die from humiliation and lived to tell the tale. Read our funny story about it over here and learn what to do when your kids walk in on you! (It's terrible advice, really, but sometimes you gotta' do what you gotta' do!)
