Sorry, no. I'm not saying you are immature unless you can compartmentalize all emotions.

I'm saying that mature people are able to compartmentalize at least some of them in their day to day life. Losing a child or some other insurmountable horror is excluded.

What I'm talking about is if you have a bad day at work, you don't yell at the poor cashier working the fast food drive through window when you're picking up dinner on the way home.
