My mom used to do that ... I'd see her do it and say "Mom the batteries are dead" but she continued to press the buttons trying to change the channel. She even smacked the remote so hard she broke it and had it taped together with the dead batteries still in the remote to where when she finally bought new batteries had to undo all the tape to get the batteries inside the remote
Lol. I've been doing that for the past week.
Its called an elicited response. You continue to try harder to get a result that you normally do easily.
Because us stupid humans seem to enjoy breaking things!
Blind hope because sometimes it actually seems to work?
because we hate having to buy new batteries so we try to squeeze the last bit of juice out of it and hope it works
because that it would send a stronger signal.
Have you tried licking the batteries?
