Drank too much.
I was going to go to a movie but the hangover kicked in late. Was perfectly fine upon waking, but about 4pm it hit me.
Meanwhile, Nan tells me today she loved how happy I was when I called her last night. I had to inform her that when I called I was so freaking drunk. It was 8pm, how embarrassing! So now she doesn't think it's such a good thing if I'm so happy...
