Stuck in my mind!
I've been looking for this fic for days. Remus and Sirius live together/are together, but either James or Sirius isn't too comfortable with PDA. Remus comes home with good news, but then Sirius shouts out that James is there. Remus is upset that he can't be as open with Sirius about his good news, because James is there. I think James and Sirius are eating Popsicles for some reason or other. If anyone could find this I will be so very grateful! I've lurked on this site for years, and I love the works you've compiled here.
