Sam: Should I pick you up or you'll manage to find the address?
Lia: Sam, pick him up
Lia: it's too far
John: don't bother I can find the place if you send me the address
Lia: no, it's too cold and too far, Sam will be there
Sam: I can be there, but you have to wait 15min at least
Sam: also it's not easy to park there, so it would be nice if you stayed outside, so I could just pick you up
John: ok, I will wait at the bus stop
John: I have a big black suitcase, you can't miss it
Sam: perfect!
Lia: let me know if everything is ok
Lia: I won't be home before 7, unfortunately
