I mailed 7 postcards today. It made me feel like a champ.
It turns out, funny-shaped postcard have to be placed inside plain brown envelopes in Japan before they can be mailed out of country, so if some of my recipients get boring-looking envelopes, never fear, there is a cool postcard waiting inside.
Also, turns out Japanese envelopes don’t have the sticky glue flap that you lick. Instead, the mail workers give you a glue stick to seal your envelope with. I know, because I licked my envelopes for about 2 minutes before I realized I was just licking paper, much to the distress of the Japanese housewife who was sitting beside me writing letters at the post office.
