It’s a weird thing to note that people think that if you do not react obviously and loudly, you must not have any emotional reaction at all. At what point did it become necessary that you should have to poll observers for their expectations of your reaction so that you can react in the approved manner.
I’ll react in my own way thank you. I can’t think of anything that would annoy my parents more than the knowledge that I spent too much time crying over them rather than living my life the best way I know how.
