Why this long?

Student: I have send you the paper to edit it.

Me: Yes, I got it; thanks

Student: When can I see that you have read the paper and edited it

Me: It will take me some time. I have a lot on my plate but hopefully by next week

Student: umm...but in the group you only have one paper that needs to be edited (which is mine). Why would it take this long?

Me: You don't know what I do all the time, do you?

I am not sure I was that oblivious when I was a grad student. If I was, time to give my grad adviser a call to apologize
