I've looked up a soup recipe, searched multiple church websites*, added some books to my Amazon wish list (which I'm pretty sure only I look at, but it gives me a strange comfort to know it's there), perused Oprah's suggestions for memoir reading...
Amazingly I've stayed away from youtube. And if I was currently on facebook, you wouldn't even have to ask what I'd been doing with the last three hours.
Just FYI. If you ever tell yourself, "Oh I think I'll do some homework on Saturday night," you might find yourself doing other things instead.
*specifically, I've been listening to sermon podcasts to see which pastors' voices I find to be the most convicting. Not in a creepy way, just because that has a lot to do with my choice to listen and thus gather something from a message.
