Hi, Gleb! Recently you wrote in a message to Ardith Hinton:
BTW is it okay to use "hang around" without seeming a bit
too "informal", or should I have said "stay"? :-)
Once upon a time I was taught to use formal English & I think the same also applies to many others here.
In echomail we tend to write less formally, as native speakers do when they don't have to prove anything to Miss Stickler or whomever. If you feel more comfortable with informal terms that's okay AFAIC. If you've made what others see as usage errors & they try to help that's okay here as well. However, I was not objecting to your vocabulary. The words you used tell me significantly more than the alternative in your question.
WRT this example, I used quotation marks to inform you I'd regard "hang around" as colloquial. Not all dictionaries mention such things. :-)
