How do you cheer yourself up after a crummy day?

[Amanda]

I've had run of crummy days and I'm out of ideas. It feels as if everything I do goes pear-shaped. And I don't really like pears.

Pen related: I already ordered a pen this week (for Christmas), but the ink that was ordered to go with it was back-ordered, drats. I did the grownup response and chose a different ink which will be a gift for someone else. Sigh.

What do you do to cheer yourself up? (Preferably, but not limited to, simple, inexpensive and plague friendly.)
