There's nothing more awkward than when a bit-too-friendly cosmonaut serving with you on the International Space Station finally asks you out.
Caught off guard by his forward request to join him for yet another viewing of "Contact" followed by a romantic spacewalk, you mumble an excuse about having to wash your hair and try to quickly float past him to the nearest hatch.
The showering cop-out isn't just weak sauce because it's an old sitcom trope, but it's gotta sting all the more with the knowledge of the fact that there is no traditional showering on the ISS.

In the YouTube clip below recorded on board the ISS and posted Tuesday, she demonstrates her process for washing her hair in zero gravity.
Turns out, it probably makes for a much better excuse for dodging a social engagement in space than it does here on Earth. That's because a thorough shower in space can easily take the better part of an evening when you must continually grab at water droplets that are floating away and chuck them back in your direction.
