I debated whether this deserved the fiction heading or not, but decided it was too much of a stretch to call truth. I am notoriously bad at staying up late and have spent the night on many a friend's couch/spare bed/floor and in this case my friend did decide to sleep in nothing but his skivvies. However it wasn't really something that a big deal was made about. He asked I cared, I said I didn't, we both went to sleep. Despite my parents' concerns of male friends taking advantage of me, with the exception of once, nothing even remotely untoward has ever occurred and in that one exception, nothing a couple choice martial arts moves couldn't resolve quickly.
