Your personal space will be invaded in the city setting. Greetings consist of a kiss on the cheek and a light embrace for girls to girls and guys and girls, and a handshake/brief embrace for guys. Learn the proper handshake if you’re a guy. It took me a while but once you learn it, you’ll earn some respect and look less like a foreigner. People will not be shy about giving hugs and grabbing you to show you something so just observe and follow what everyone else is doing, but just know that there isn’t an emphasis on personal boundaries.
