Crying at something sad is not 'falling apart'
Why the ridiculous association with crying as a massive weakness - a failure to control?
Crying is not wailing and thrashing around on the floor. It's just crying.
I have two adult sons and a 12 year old. I cried in front of them when something made me really sad. I wasn't constantly bursting into tears but controlling my sadness in front of my two year old when my dad died would have been impossible and, for me, deeply weird.
My children are all open, happy people who discuss their emotions, when it's appropriate, with openness and intelligence.
Making happy, sunny, positive the only 'good' emotions and sadness the one that needs to be controlled and hidden does not sound terribly healthy to me.
If one is not naturally a crier that's fine, but to hide, as if shameful, something which is neither traumatic nor bad, is unfathomable to me.
