Sounds like a pretty straight forward question - but I guess not to a 14 year old.
When we were at the docs the other day, the PA asked Colin, "so, how are you sleeping"
Colin so innocently answered, "well, sometimes on my stomach, then I might switch in the middle of the night to my side, or to my back. So, I really can't say for sure how I am sleeping"
Both me and the PA laughed so hard.
