I love that you covered both languages too. Are there differences in etiquette between the country you're living in and the country you're from?
Introduce men before women
Introduce a girl before a boy
I've never come across this before. Is that something traditional to Panama?
I saw it on a video when I looked up rules about greetings. I hadn't heard it before either. It was some etiquette rules on two different videos.
One main difference I can think of is it is common here to kiss people on one cheek when greeting or saying goodbye. It can also happen when you meet them for the first time.
