Last year, I said I would post to this ask occasionally if I ever found letters that were of my liking.
While technically an email, this letter is one of my favorites ever and I can't believe I've forgotten to post about it here. Such an internet classic. Here's an excerpt of the Bible:
For those of you that have your heads stuck under rocks, which apparently is the majority of this chapter, we have been FUCKING UP in terms of night time events and general social interactions with Sigma Nu. I've been getting texts on texts about people LITERALLY being so fucking AWKWARD and so fucking BORING. If you're reading this right now and saying to yourself "But oh em gee [first name redacted], I've been having so much fun with my sisters this week!", then punch yourself in the face right now so that I don't have to fucking find you on campus to do it myself.
You can read the whole email linked above. TW for slurs used. But other than that, this belongs in a museum of the internet.
