Javier, hey, bud. it's great to hear from you and even better to find you you're doing well. we just got off vacation in the islands, and it was awesome. i'm sunburned, tired, and a little sorry that it's over. you didn't mention what you did this summer. anyway, when i was snorkeling we saw some hammerhead sharks. it freaked me out at first, but they were little and pretty much left us alone. you really need to get out there some time. it would've been fun if you could have come, too. i have to get going, i still have a billion things to take care of. hit me back soon. freddy
