Do you know where your towel is?
Then there’s only one thing to do: Click the banner, pay attention, and tell me on Monday how your day was (please count the weird looks).
Get into the spirit of the thing.
Yes, you should really carry a towel with you all day. You might get teased or looked at weird, but then you can just hide behind your towel until the offensive people go away. (These people are mind-bogglingly stupid and think that if you can’t see them, they can’t see you – daft as a bush, but dangerous otherwise.)
