Sour Bubble from the man, the legend, BOG

Any mail sent from Canada must have Canadian postage. Any mail sent from the US must have US postage. If someone sent me US forever stamps, I can’t use them to send anything because Canada post doesn’t accept US postage, and if I sent Canadian stamps to the states, that person wouldn’t be able to use them to send anything cause USPS won’t accept canadian postage.
