Sorry to post so late.

This Sunday (tomorrow), Aoi and I will be playing tennis at Columbia University at 3 p.m. We didn't reserve the tennis court, so it's free. I believe there will be nobody playing at 3 p.m, so it should be ok. Please feel free to join us. We'll probably play till 5 p.m.

(sorry for typing in English. I'm posting this from school, so I can't type in Japanese)
