Pop-Pop

My grandfather has cancer. A form of leukemia, I'm told. He's been undergoing chemotherapy this week, and that's really taking a lot out of him right now. He'll have three weeks until the next round, and I hope he can get some of his strength back in that time.
It's scary. But Pop-pop's always kept himself in pretty good shape and been active, so he has that in his favor. But I'm still worried, of course. My thoughts are with him, and with Nana.
