Haha, welcome to menewsha. We typically have pretty good sentence structure here so you don't have to worry about that. Granted there are people with English as their second language as well.
Interesting username, I don't think I've actually gotten a phone call at 4 am in a long time o.o
Grammar is my weak point since I'd never learned it properly as a second language, but I hope that my sentences are at least decently coherent.
I don't think I've ever gotten a phone call at four am...but then again I probably would have been too out of it to remember it by the time I actually wake up properly. I've been known to forget things completely if talked to before I'm fully awake...
