It does feel strange testing for two recipients, but when the second contacted me I informed her right away that I was already considering being tested for a patient. She asked if I would test for her as well and choose either the patient who is the closest match, or if there is no preference, the patient who first contacted me. I agreed, and now it would be impossible for me to choose just one to test for. I will most likely choose just one patient to continue testing for once the compatibility tests are finished, though.
As for why I'm donating to the US, even though they are in a different country, I live in southern Canada and they live in northern US, so it's not much farther than any other major Canadian cities. I know that distance is always going to be a concern for me because I move around so much. No matter where I donate, there are always going to be issues of needing to travel for the surgery and the testing. And I don't care about donating to another country - a person is a person. I made sure both patients understand that asking for a donation from a Canadian might add an extra layer of complication, and they are both fine with that. They seem like really wonderful people and I'm just glad I'm able to help.
