"I didn't wake you up today. Don't go to work (you'll probably be late in any case when you're reading this). Just take some time off today and heal. If you're going back to your apartment, I've kept the other pair of keys I have on the dining table. You can lock up.

I'm glad you confided in me, although you didn't have to. I feel like I'm back to being the good friend I was to you from before, for real now.
