Don’t Get It

He says he doesn't know how to count, skips various numbers, and the other person doesn't get it.

Its pretty vague to just start out on 37 though. I mean is 37 the first thing you may not know meaning he literally doesn't know what order numbers go in to count? or were there 36 other things and and he can't "count" how many things you may not know about him. His next comment is 38, implying he does know the order making it the latter option, yet the last comment is 42, implying he doesn't know the order making the former more likely.

The poster never commented it was someone else
