OMG thank you for the long reply! I am not malaysian nor singaporean I am filchi (filipino-chinese), and sometimes I pick up singlish words bc I am friends with sg / my peeps (fandom perks). The thing is, my friends don't want to teach me bc they said we can communicate in english so why bother --
Ohhhhh! I see ;O; funny I have a classmate who's half Filipino and Half chinese too! That's just sad that they won't help you at all :( well I can say watch some chinese dramas it can probably help too ;-; not China ones but maybe Taiwanese ones ;; (the slang is not as heavy) and I think easier to find with English subs! I hope your friends are really not going to just think less of you just cause you don't understand the language, cause it's not your fault ;-; and yeah, you can still communicate in English :) don't think less of yourself either!
