I’m fairly certain she didn’t lose the ability to laugh. I don’t think that’s entirely possible. Either you weren’t as funny as you think or she was awkward and nervous and that suppressed her real laughter. Or, hang on, there’s a third option which is she’s rotted her brain by being terminally online to the point where real experiences lose their meaning. Actually now that I think about it, that’s probably what you’re getting at here.

Fuck, wait a minute, am I losing my touch with reality and human connections?
