Yeah it's almost like it's a casual conversation, huh? I wonder what might be the cause of that. I wonder what might cause someone to be very CASUAL about the CONVERSATION. Almost like someones trying to stimulation conversation CASUALLY.
Meanwhile here you are with your own extremely strict interpertation of what a casual conversation is and trying to enforce on everyone else.
I'm just going to go back to not knowing you exist.
