When I was a kid and would send very stuffed letters, we just left a dollar paper clipped to it, they would leave the change the next day for heavier stuff.
When I was even younger I used to leave flowers in the mailbox for the mail person, and they got me a little flower statue for xmas and left it in the mailbox for me. That’s a memory I haven’t thought of in a long time so that was pleasant :)
Hahaha I had the same experience learning Russian. It’s so hard to find simple stuff like dick and Jane, but in another language.
Interestingly, comic books, especially those which have been translated into multiple languages (marvel, dc, etc) are almost easier. They usually have short, less-complicated sentences, and the context is pictorial. Plus it’s not boring af to read, which is ultra-helpful. Maybe that’s why people like manga and anime so much…? Idk.
