So every few months I start to feel pangs of guilt over losing touch with my host family from when I went on student exchange to Korea. Shortly after I returned from my exchange, my computer broke down and I lost my host brother's email address. I feel particularly awful about losing touch with them because my host brothers were 5 and 7 (their family was a last-minute stand in for the family I was supposed to stay with) and I worry that they've taken my lack of correspondance personally. I want to send them some snail mail to get back in touch, but I haven't been able to find anyone who can tell me if the information I have is adaquate. I know the name of their apartments and their suite, and that they're in Cheonan, but I have no postal code. Is there anyone out there familiar with the South Korean postal service? I also have their phone number, but only seven digits with no area code. I would be eternally greatful to anyone who can help. Thanks!
