I Have What?

Little Man: Mrs. L! Your arm is all red! Are you dying?

Me: No, no of course not Little Man. I just had an itch.

Little Man: Oh. I bet you have fleas.

Me: Fleas?

Little Man: Yes, when my dog is itchy my mom says he just has fleas. Must be that's why you're itchy.

Me: Must be.

Do you think it was bad that I told a little one to ask his mom why d!ck was a bad word? I reeeeeeally hope he doesn't ask her because I can only imagine what the conversation will sound like.
