if i write a letter i'll just write out song lyrics to make it longer
idk why i send letters sometimes i just feel like it
sometimes i send letters to my 2nd/3rd characters so i can pass stuff to them easily (and remind myself to go on it the next day when their mailbox starts beeping) and i'll have spare letters so i'll send one to someone and attach the other letter to it as a gift
My brother mocks me for this, but I actually write my villagers letters all the time. I have a system to it. If someone writes me a letter, I have to write them back. I don't have to respond to their next letter, unless they ask a question. Then I have to respond.
I write maybe once a month. I used to write daily until I got my gold badge, then I got lazy >< I always write to them on their birthdays, and on holidays like Valentine's and Christmas. I also write welcome letters and goodbye letters when villagers come and go.
