Yes. I am nearsighted. No. I do not always wear my glasses.
The other day, I was helping the Bug get some tunes going on Pandora. Not a big deal. It just involved looking back and forth between the remote and the TV to type and make menu selections.
As the station was loading, I look over to see the bug, with another remote inches from her face, squinting her eyes just about shut and raising her upper lip enough to expose her top row of teeth while she slowly pressed buttons with her thumb. My vision isn't that bad.
Another fun thing to do is say "big daddy." Not just say it once, or even ten times, but to repeat it on a loop measured best by minutes. "Big" must often be emphasized by volume, duration, and fully extended arms.
