Ego got in my way so I ignored. This is not what I wanted to do. What I wanted to do was say hi like he never was gone. Not full of emotion, just "hi".
Gerda, the ant analogy is a good one. I can understand what you are saying. One behavior or response will not dictate what he does or doesn't do. All I prefer is that I do not push him any further out the door.
Dnj, you are right, common courtesy with a "roommate" would be to say hi upon a return. I do not know if I could say anything about letting me know when he will be back, but like you said, if the opportunity lends itself.
PT, I will look up Ha Who. What I could've said? I don't know. Maybe just saying hi. Then I wouldn't feel like a kid. (well he doesn't say hi so I won't) I am an adult. No need to be at his level of rudeness.
I need to remember all of these thoughts when I am presented with this situation.
