What To Do On Rainy Days

It has been raining non-stop for a few days. Luckily there's no flood at my hometown here. But what to do on a rainy day?
For me, if it was raining when I'm waking upon that particular day, I will just resume my sleep and lay in my bed with my cozy blanket wrapping me. That's, perhaps, was the best thing to do during a rainy morning, where the weather is just perfectly cold enough. So I'm going to resume my journey in my wonderland. Buh-bye and good sleep.
