Tuli said "Between you and I
Should be 'between you and me'
Your welcome
Should be 'you're welcome' "
Be careful about correcting people that use the word "me" instead of "I".
For instance, "My parents visited my wife and I" would be improper use of grammar. The correct way would be, "My parents visited me and my wife."
I is used when it is the o:bject, and me is for the subject.
I know it takes this use of I/we to a deeper level of grammar, but my pet peeve is when people THINK they know their grammar.
