Farewells...do we really mean it?

It's a week of farewells at work, with 2 colleagues leaving for yet better hellholes. And it got me thinking....
1) Why are we giving farewells when those colleagues are leaving for better job with of course better salary (or else they wouldnt have left)? We should be CELEBRATING and those who are leaving should be buying US ...and not the other way round! Think about it, you give false congratulatory remarks..when deep down you're wishing you're the one leaving..hahaha..and cursing the guy's luck thinking you're WAY more qualified than him.
2) DO we need to give farewells for colleagues you are not close to? I mean...you and her/him never hung out together BEFORE he/she resigned...so now you have to attend his farewell party? Doesnt make sense...does it matter if you attended or not? Would he/she even NOTICE if you weren't there? And if you weren't there, do you care if he/she is gonna be offended?...afterall, you're never gonna EVER see him again.....hehe
3) And if you were close to the person leaving, is a farewell then necessary? Are you gonna cut friendship ties just because he/she is leaving the company? If so, what does that maketh of your friendship with him/her? SO friendships made at work are ingenuine?? You leave the company and we're no longer friends...our friendship expires here......! Makes you really ponder WHO in your company are JUST COLLEAGUES and who are FRIENDS...
4) I always thought farewells are like funerals ...not a fan of it...but more recently I just think of it as an excuse to 'makan" and get together.

Well..I dont usually bid farewells...or wish them better luck..blah blah...say it when you mean it. and mean it when you say it.. I think farewells are really for saying goodbyes to the dead..coz you're NEVER gonna see them again (in human form anyway). The rest of y'all leaving this rathole, well...you're leaving for a better place...so you're not getting a farewell treat from me!
