Most of the Colombian people l met were wonderful, although shy at first. If its your first meeting they tend to shake your elbow with their hands. l know that sounds strange, if you have met them a few times the girls will kiss you once on the cheek the boys however want to stick their tongues down your neck... ...that was my problem.. lol...A very class conscious country they tend to ignore people who are not on the same par as them. Most households have maids who in fact are treated well and given the opportunity of going to night classes. A lot of very very poor people in this country whom l had the pleasure of meeting where in fact nicer to me than those with money. They were not interested in my education or what part of the city l came from. More interested in finding out why my hair was a different colour and laughed at my spanish in a nice way.
When greeting someone, say:
'buenas' and not 'hola' like you saw in your Spanish text.
Say 'chao' (pronounced: 'chow') when you say good bye.
If someone bumps you and expresses pardon say to them: 'fresco, fresco.' This is a Bogota expression that means 'that's alright' or 'not a problem.'
