Y'all, I thought of a p.o.v. kind of thing earlier:
You and Lily Potter are best friends, but of course, she's not a Potter yet in this short tale, since you're still students. During your 2nd class of the day she whispers as quietly as she can over your shoulder: "Hey (Y/n), do you have a pad I can borrow? I didn't bring extras." You pass her one as sneakily as you can and then meet her in the hall after class.
"Thank you so much, you're a lifesaver, honestly!" (I thought of this marvelous pun, too)
"It's alright, really! I guess from now on I'll just bring extra Lily-pads. ( ͡° ͜ʖ ͡°)"
