...how the hell am I supposed to deal with everyone getting not just old but crazy? nobody ever told me that old people would more often than not end up being fucking nuts! And yet my mom, the one with, you know, an actual neurological disease literally impacting the brain, is the sanest.
'Believe' is not the right word here. If you believe in chairs, it means you think that they exist. If he doesn't believe in chairs he's a nutter, if he doesn't worship chairs he's a normal person. The only other interpretation is that he doesn't have confidence in chairs, like maybe he fell out of one too many, which would also be very strange.
