Where are my clothes? I blackout often, as you well know, and have woken up in many different places under many different conditions, yet even in situations where I awake without my clothes on I know where they are. Beside a bed or next to a hot tub or hanging off a lamp or whatever is acceptable World. But waking up in my own bed alone without any sign of my pants is not cool.
Please take steps to ensure this kind of thing doesn't happen again.
