Someone in your company brought a frozen Oreo cheesecake. There is a quarter of it left. Instead of sharing with your officemates, you smuggled the piece out of the office to give to your train buddy/gal pal and her coworker (who is fast becoming your friend as well) in the building next door.
That, and the fact that your mom made homemade Mexican dish for you, plus a whole extra container and all the fixings for your gal friends in the building next door.
Ernie Next Door. We love you, man.
