Spanish customs

let's talk about some of the most famous spanish customs:

1)greeting: when somebody introduce you a person or when you meet a friend you normally kiss the other person twice in his/her cheeks, one kiss on the right side and another on the left. Except if a man meets a man, in that case you only shake hands. You normally do the same when you say good bye (so if you come to Spain and someone tries to kiss you don't be scared hehehe).

2)siesta: the siesta is a short nap that we have after having lunch and it last normally half an hour. There are some people that don't do that, like Sergi, but I'm a very fan of it!! :P

mmm well, now I don't remember any other important custom, but as soon as I remember I'll post it :)
