This happened to me last night when I tried to sleep on th futon at the beach house my parent's are renting (I couldn't sleep on it at all although I did go sleep on their bed for a while after they woke up and slept a few hours there) so I told them that I will be returning home tonight rather than spend another night at the beach house as I had planed on doing, it doesn't bother me much because I have already gone to the beach a few other times this year.
