don't want to blend me into that topic, but
"canceled because you think the rules don't apply to you and you are a headache."
and
"canceled because you think the rules don't apply to you and are a headache."
are two different things.
One is calling you a headache - one is calling the rules so , i was shocked by the fact that he was calling you something personally, like "you are a pain in the a**" but in this case he is not offending you.
Make sense ?
Lettered, numbered, what you can or could - i am out here, as i do not know what is common, but this little "you" made at least a difference to me.
