Eh Awkward?

Ok so as I've said before me, my dad & my sister have recently gone on this silence spell. My dad has introduced mini conversation points like good morning, & I've allowed...hi's & byes. Small talk even when I'm in a good mood but since he has yet to mention the incident & probably never will I've pretty much just said screw it. We can be civil & say what needs to be said but I'm keeping my distance. Anyways tonight I was in the kitchen & my mom said goodnight to me when I was about to walk out the room & I didn't say anything to him because he didn't say anything to me but to me it was strange that no one said anything. Maybe I'm the only one that felt strange but who knows. To me this whole thing is just weird but at the same time I said I refuse to be the one to fix this situation & I'm sticking to my guns.
