Neither. Mostly I just walk away. Turning the other cheek is allowing the person a second chance to hurt me. Getting revenge feels like too much work and aggravation. And perhaps danger.

Walking away from it makes the most sense.

Turn the other cheeks.

I've never believed that turning the other cheek has much benefit. If you keep turning the other cheek eventually people will start to think it's okay to take advantage of you.
I wouldn't call myself vengeful though, unless the situation is severe enough. Most of the time I just hope that karma will do the job for me.

Sometimes neither because I don’t care.

Peace is better than friction.

Revenge...

very vengeful
