Hey all puas

what up?
I got one of the most used and most boring questions on text. "How have you been?"
Date: 7/4
ME: Hey *****, I hope you got home safe.
//Simon from the balcony
Date: 10/4
Her: Simon! Sorry for the awfully late reply, but thanks for the worry, got home all safe and sound

How've you been?
/***** from the same balcony
I have already replied with the line under
Wow, you are still alive. Now we can hookup but, only if you're nice back to me. (saw this on the forum)
BUT, I still want to know what could be a good response in the start of the conversation if somebody asks what's up? (as I said I do not like to answer good and u?)
So what can I use as respond?
Peace Gigolo
