My social life as a grad student

My parents and grandparents visited me last weekend. My grandma seemed to think that I should be spending more time with my classmates (out of class, that is). A day or two later, I got a party invitation from some of my classmates. (No, I'm not going to the party.) I got a follow-up email today:

We have the keg now, and as a general policy, we don't not drink a keg when we have one. So, the sooner you come, the more beer you can drink. The more beer you drink, the less you'll realize you're at a party with all accounting students.

So, I'm pretty sure this is not what Grandma had in mind when she was asking about whether I do things with my classmates!
