Or is my brain just bad?

like, not a lot, but I often have to stop for a literal second to think what letter comes next

I never have to do that with a number

oh no I often have to stop and recite the alphabet in my head for a moment too. It's a longer string of Things with no discernible pattern to them.

yep

yeah I mean there are 26 of one and only 10 of the other

also numbers are ordered the way they are for a coherent reason

like, 7 is larger than 6. H isn't larger than G

yeah i have to do the relevant bit of the alphabet song quite often
