Blindly flexing

It's flexing but the person doesn't exactly notice. You do though, it makes you feel bad about yourself, sometimes.

Lily: "Oh my gosh! My 2 Ipads couldn't work, so I brought 2 more. And remember when I was in 1st grade? I dissected a cow eye!"
Me: "That's cool, I guess. You also already said that story of dissecting a cow eye over 100 times, I don't want to hear it anymore."
Me (thoughts): "She's blindly flexing again . . . "
