Well done, sir!

I'm so glad that you're enough of a man to come talk to me if you have a problem with me or something that I did, instead of stooping to the middle school antics of some of those around you. To burn a bridge with a future colleague in such a fashion would be completely unexpected from someone of your age and experience...

Really, I should thank you for teaching me a valuable lesson about trying to be there for people one thinks his friends. Next time I see one of my friends about to jump off a cliff I shall force myself to keep silent... 

Whatever your endeavors, best of luck.

(A message from me to a colleague in a not-so-subtle way saying you're acting like an ass...)
