Aparecem!
Literally translated this means - 'Drop in'. When we lived here years ago, people used to say this to us all the time - but I was never sure if they really meant it.

In addition, I really never came to terms with the 'dropping in' culture. I can remember once, having briefly exchanged some pleasantries with a young couple in the street who were interested that we were English, and the next thing we knew was that they turned up on our doorstep, expected to be invited in (which we felt we had to do) and stayed for hours. This used to happen quite a lot!

It's interesting that here we are 30 years on and haven't once had someone say to us 'Aparecem'. We have been wondering why this is and have come to the conclusion that it must be because 30 years ago there were not only no mobile phones, but virtually no phones. We did not have a house phone. This meant that you couldn't phone people up and arrange to see them - you just had to 'drop in'. There are, therefore, some good points about mobile phones. This is from someone who hates phones in general - give me email any day - although I have to say that I have enjoyed having Skype during our stay here in Brazil.
