If you're not sure what to say, try "so, it has come to this" - it creates instant dramatic tension and is a valid observation in literally any situation

The best way to deal with an insult is to ignore it,
If you can't ignore it, top it,
If you can't top it, laugh at it,
If you can't laugh at it, you probably deserved it,

I don't actually lol
I laltis...laugh a little....then I stop
