Being drunk doesn't make you blinding stupid but it sure as hell makes it hard to type anything coherent. I spent like 10 minutes trying to tell my friend that I was drunk by text.
eh, i think that's more of a subjective thing. when me and my ex used to be together, she'd be texting me almost all the time. whenever she got wasted it would be something along the lines of, "oh ym goaaddd wer r iiiiiiiii (you) ciom hsng (hang) pkt (out) wirh meee"
whenever i would get trashed, i'd text perfectly fine. in fact, i've been on the forums many times drunk and nobody's mentioned anything
