'Open when...' inspiration

so im not sure if you have seen my post if not here's a link explaining whats going on, im not gonna repeat everything so i don't appear redundant.

https://www.7cups.com/forum/hobbyzone/Writing_839/Openwhen_312822/

so basically i want to know, what important life moments do you think someone should have a letter like that about?

such as 'open when you are sad' , 'open when you get your heart-broken', and 'open when you become a parent'

i want feedback from my community <3
