I speak English very good!

Is it something to do with the word misses and it should be "like a child would miss their blanket"? I can't figure it out if it's not.

I was under the impression that the problem was that 'their' should only be used as a plural and here it is being singular. Meaning the sentence should read "I'm going to miss you like a child misses his/her blanket.", but I personally prefer the use of their/they in this kind of situation.
That was the issue, right?

i think its part lazyness..
i havent had english in quit some time @ school. and if i have english, than its nothing.
What i type is problably full of faults. But im not that much bothered by it.

about: Its vs. it's
thats just one of those lazynes things, i dont always bother either to put a ' between it
and every languag has it's 'internet languag' where they simply shorten things up to save a calorie :P

Unfortunately when I see blatantly incorrect grammar and spelling in a someone's writing, I read it as if they have an unintelligent sounding accent, which is rather judgemental and rude now that I think about it xD
