I`m not a close mate of Colin but I`ve fucking served on various Committees for nigh on 50 years and understand the need to stay quiet at times.Has he really upset you,that he and others know something in advance of you ?
Grow a fucking pair of hairy ones.
You're in the clique so you wont have any warnings for your rude, aggressive behaviour but you need to calm down. I don't care if you are Mr Committee of Comitteeville, he knew what he was doing and he was wrong which someone pointed out he admitted after. If you have the info but can't say anything keep it to yourself until you can. Why is that so difficult for stress heads like you to understand?
