Swapping additional office hour

Dear group members of text-to-image,

I am trying to sign up for an additional office hour for next week on April 30, but have found all slots to be taken. Given that you have already had 2 appointments on April 23 and 25, it would be great if I can swap the slot on April 30 with you so my group can have a chance of meeting the instructors just like you did. Thank you very much.

I added more slot this Thursday. Let me know if you still cannot make it.
