When is the woman’s hospital appointment?

M: We are going to the movies tomorrow afternoon at two. I wonder if you like to come with us.
W: I’d love to, but I can’t. I ’ye got a hospital appointment at 2:30.

W: I’ve noticed that you got some letters from Canada. Would you mind saving the stamps for me? My sister collects them.
M: I am sorry. My classmates have already asked for them.
