I love the power of friendship osmosis.
“I don’t really know much about this thing, but my friend likes this thing. So by the transitive property, I like this thing and feel defensive over this thing on behalf of my friend. And if I see this thing while out with other friends, I will excitedly point it out and announce that it is the thing my first friend likes. I will also feel happy when I see it, as it reminds me of my friend, and time permitting, I will take pictures of it to show my friend later.”
