Sometimes his wife got this look where she pinched her brows together and bit her lower lip and stared down at something.when he saw her like this he knew he should keep his mouth shut, but he never did. Actually it made him talk more. She had that look now.
I think it sould be written:...when she pinched her brows...
It is new to me to use "where" in such a sentence like this one.
Thank before hand for your help.
This context is from a short story named: Say Yes by Tobias Wolff.
