Sometimes I see a post and enjoy it, but then I see the number of likes the post has and think, "Yeah, that's about the right number of likes for that post" so don't like it myself.
Sometimes I accidentally like something while scrolling on my phone. Never mind, clearly that like was meant to be. I'll let it stand. What have I liked, anyway? 'Skull physiognomy is the real decider of elections'? Oooh, boy...
