i have seen him yesterday" is fine, fight me

lol every week someone posts the same grammar list and i'm like... did anyone actually get confused when someone said that? no. you understood them perfectly. that's the whole game. ngl the "i am agree" one makes me laugh too because it's so obviously just korean brain doing its thing, but you fix it by talking, not by memorizing another rule. textbooks are two decades behind, fr. just say it, make mistakes, get the point across. that's fluency 😭 (jk no emoji, but you get the energy)
