Tobias: Are you already in Belgrade?
Mary: yes, we've landed a few hours ago
Albert: Safe and sound, now in the hotel
Tobias: how is it? the city I mean
Tobias: Do you like it?
Albert: We haven't seen much yet, we're both quite tired
Leo: I imagine, jet-lagged 
Albert: yes, it's always worse to come from the US to Europe than the opposite
Leo: so true
Albert and Mary are in Belgrade, but they haven't seen the city yet because they're jet-lagged.
