But you must admit that some shortages are great:
YASP - yet another sunset picture (it was somewhere here some time ago)
In Poland we DO have shortages and slang, but whenever I tried to translate it exactly into English, it appeared funny for almost every Brit or American there. Some perverted things I suppose.
I know an English guy, who leaves here - he is an Eng. teacher, who actually teaches me

and he always has fun when I'm doing stupid mistakes, because in most cases the meaning is completely different.
You see, I've been learning Eng. since I was 4. And then appeared a funny, and a bit annoying thing: first I learned to write in English, then in Polish - my own language. So I feel quite confident in Eng, but I have many problems with slang

both - American and English. Also phrasals makes me feel bad

uke-rig:
I don't know who the hell created them

maybe for you they are extremely easy, but for me they are the same verbs only with different ending - all meaning almost the same

I have to learn them by hard.
