It's pretty cool that I can have mathy conversations with people on my hall; it takes a special kind of craziness to enjoy arguing about the difference between supremum and essential supremum at 2 AM.
That said, I really need to learn to say, "Can we talk about this an hour from now?" because I really shouldn't be letting a single math question hijack a conversation. I'd prefer not to take my obsession to the level where I make people feel excluded for not being math majors. (I hope that hasn't already happened.)
h/t to eyefragment for planting the seed of this thought in a comment thread sometime and somewhere; I suspect the comment, wherever it is, actually looked real similar to this.
