Nick, Will, It Doesn’t Matter
Getting caught in the act is never fun, especially when you’re caught by a parent whom you’ve never met in your life. The OP got to meet his GF’s mother for the first time while hiding from her. Their act was interrupted when the mother came home unexpectedly.
However, she wasn’t all scream-her-head-off crazy about their little interaction. She was completely cool with it, and she even asked Nick how he was doing. Who’s nick you ask? We don’t know. The OP’s name is Will. This brief conversation with the mother probably raised a few questions the next time Will and his GF met.
