Today my teacher told me that when there are two girls having a conversation the only correct version is:
This guy is so hot! He even asked for my telephone number!
While I think that version
He has asked for my telephone number
is also correct, because they aren't talking about specified time - it happened, but it's not in the context of specified time, place etc.
Obviously, nobody would care in common conversation and everyday's language usage, the past simple version would be better in common usage, but I'm just curious if my teacher was right or not.
