And apart for having moral support it was financially sound. When I was doing well with my freelance gigs I would contribute to the household and everybody enjoyed the fruits of the excelente USD to MXN exchange ratio, when work dried up I knew I wouldn't starve.
There's always a character in US sitcoms that lives with their parents and is portrayed to be such a loser. I just don't get it.
I guess, what I say is: if you want to travel around the world do it. If you want to live alone or with annoying room mates do it. But if you're happy with your parents (and vice-versa) why does the culture wants force you to be miserable and alone?
Screw the culture.
