samcro - on the assumption that you were asking a genuine question then the way to tell when you use "lose" and "loose" is to think about the past tense of lose = lost = 1 o. If you lose this, it will be lost forever.
Lose --> lost.
Loose does not go to lost. Also, loose rhymes with goose - and you don't say it like that if you mean lose, because lose is pronounced luze.
ghostspirit has given a good way to remember brought and bought in similar fashion, but using the present tense of the verb to differentiate -
bRing and bRought,
buy and bought.
your and you're - extend the you're to you are and if it works, then that's what you should use. If it doesn't work, then use your.
So - you're joking aren't you - you are joking, aren't you = correct use of you're.
Your = same as my only belonging to you, not me. Your hat, for e.g. Not you're hat because that would be "you are hat". Which, in general, you won't be.
While I'm on a roll, if anyone has trouble remembering when they should use a c or an s in words like practise/practice - think of the words advice/advise instead (because they're pronounced differently so easy to tell the difference).
Good practice/advice = nouns.
I'd advise you to practise more = verbs.
I'll bugger off now.
OP, I think it's U to call all corrections personal attacks unless they're in the context of being mean and belittling - but when they are, then yes, they should be deleted.
