I try to figure out the structure of this sentence. but I'm somehow confuse with it
what I got is this
忘れちゃうと いけないから、 in order to not forget
メモしといたのに although noted it already
そのメモをなくしちゃった that note is gone (lost it)
(If I got it right) it seem make sense to me but in grammar first two sentence is strange.
is it like this? ... although I noted it already (in order not to forget) but I lost it.
