A few years ago I went to a nice restaurant and got the shrimp, however the chicken looked much better. I would change my order

Nothing

It would be easier to list what I wouldn't change...

Some relationships maybe...

Everything.

So many things...

My marriage

Stop my wife's smoking.

Maybe change some things hinge about my divorce and custody arrangement.

Nothing I feel like everything has happened for a reason

My wife dying of cancer.
