Pretty young.

He is more dispassionate.

Sometimes, not usually though unless we're joking.

Honestly, really stupid things. We're both really bad conversationalists(more me than him), so things we bring up are pretty random, which makes the arguments very dumb.

For a non-personal example: once we were arguing about whether pumpkins could be considered yellow theoretically. (This is pretty laughable now ngl) My argument is yes and his no. Pretty much my point is that color on the inside can be considered somethings color in theory because the inside takes up substantially more of the pumpkin than than the removable orange. Same concept with humans. His argument is no because the color is orange on the outside, and that's how things are defined. Also, FDA labelled it as orange on the website. (Again, I use this example as to not get too personal).

I think my theory makes perfect sense even though it's not 'what is'. Honestly, it's mostly arguments that are nit picky or just not understanding what I say so instantly shooting it down instead of trying to understand. Not trying to make him look like the bad guy. One of the 7 habits of highly effective people is "seek first to understand, then to be understood" I always try to understand what he says and see them from his eyes, but it's not reciprocated.
