Dumb things that you did.......because you didn't know any better.

I innocently took an apartment neighbor out to dinner (for the first time) on my birthday because my wife was out of town. When we got back to our respective apartments, I said thank you and good night, but she walked over to my apartment door (instead of her own) and just stood there. After a short discussion, she admitted she was horny. I told her I was married. Her response was we shouldn't but we could. Don't worry, I eventually told my wife the whole story (the truth).
