Something I never noticed until just now in Friday the 13th Part 2

Continuing my infrequent series of articles about things I'm just now noticing in movies I've seen literally hundreds of times, let me point out a bizarre sequence from Friday the 13th Part 2.

This is Vicky, going skinny-dipping in Crystal Lake, alone, in the middle of the night. While that's questionable in and of itself, let's move on to what I'm here to discuss, namely Scott stealing her clothes-

Who throws their wet towel off into the woods when they were on the way back to the place it belongs?

Weird.
