Expats anyone? And why won't my shoulder stop hurting?

Expats:
Recently I've started to feel the desire to meet some expats down here. As you may have noticed, I spend most of my time with Portuguese- or Spanish-speaking people down here. That is important to me because that's really the only way to learn Portuguese and to keep up my comfort in Spanish. I really enjoy the people down here and the friends I'm making, but I would like to make some friends of expats down here so I can have the occasional conversation with North Americans who share more than just the language with me.

A big part of our experience in Spain was involving ourselves in the culture. I have carried that with me wherever I go because I think that's how you get the most out of it. Sometimes I wonder if having the family (namely Mom) along gave Dad that core of familiarity while exploring something new? Perhaps a conversation for another time.

My shoulder:
I screwed my shoulder up wakeboarding the first weekend I was here in my awesome fall. I didn't think too much of it at the time because... well I'm getting old and things hurt after I do fun things like wakeboarding. Unfortunately, I think I aggravated my should where I hurt it a couple years ago playing squash. 5 weeks on, it is still in rough shape. I can't put on a shirt on or wash my hair without wincing. I'm still on US insurance and I'm not really sure how that all works down here. If I were in Chicago, I'd definitely go to the doctor. I'm not sure I should keep playing squash as that will keep it aggravated and possibly damage it further. Any educated thoughts?

Off to pack for another week in Rio!
