My Dh brought me the portable phone in the bathroom one day. My Best Friend's 16 year old son was calling me. Now that was a comfortable conversation:
Brandon: Hi Pixie Dust! Just calling to thank you for the birthday gift.
Pixie dust: You're welcome honey. (trying to talk loud so he doesn't hear the background noise ... I mean you can't just stop peeing mid stream

)
After I yelled at DH, he says "Well he just got his license, I was afraid he was in an accident and was afraid to call his mother, so he called you instead"
