One time, when my son was two, he was in his car seat, and he said "What the hell is that?" I looked in the rearview mirror to see that he was pointing at an air balloon in the sky. I caught myself saying, "Where the hell did you learn that word?" LMAO I didn't even get the whole sentence out before I felt so ashamed. Needless to say, I was more careful about what I said around him. :-)
