What is a fun childish thing you still do as an adult?
For me, it's sticking my hand out of the window of a moving car. Whether I'm driving or not, I love having the windows down and waving my hand in the wind. I've loved it since I was a child and I'll never stop doing it!
Buy stuffed animals. I sleep better when I have something soft to snuggle up against, and they work better than pillows since they're smaller, and also they're just very cute.
