Nested List Abs[]

I have a list, and each element of the
list is a sublist with two integers. How do I delete from the larger
list any integer pair whose numerical distance apart is greater than
one? I'd been trying to map Abs[Subtract[#1,#2]]&<1 over the list, but
so far that hasn't worked.

Any suggestions?
