hey, zoe!
don't worry, i understand how it must be hard to keep up with our classes because of your hectic work schedule. i tried to call you a couple of times though i was also worried about waking you up. you didn't answer, so i guess you were asleep.

anyway, you can always arrange for make-up classes if you have the time. i miss having classes with you and i am looking forward to talking with you soon!

take care, zoe!
