I find it funny you quit on 9/9/09 and your name is 888 pancake.....lol.
Here's my take, for what it is worth......I think sometimes we have what is called the spotlight effect.....we think everyone is keyed into us........we have so much going on in our heads and we think everyone can hear it and knows all......I think most people could really give a sh$%. They are too caught up into their own stuff......you aren't in the spotlight and perhaps your boss has "moved on." I am in a similar situation........I am currently on seasonal layoff and not sure he will hire me back......thought about taking him to breakfast or something and explaining things........but then I thought harder and decided to just try and prove myself again.........moral of the story? Don't hand out the ammo.
Good luck with whatever you decide.
