@evan It depends on the culture & person. I usually fist bump my friends, but I also do handshakes
too.
In #Japan & some places in #Nigeria
(amongst my Yoruba tribe), bowing is how you greet someone. Sometimes we do the #Wakanda
salute for fun (only to other folks from #Africa).
If my friends are super geeky & into #StarTrek, then we do the Vulcan greeting.
