I don't cry much, I must be a Hard-Heartd Hannah. Even when my parents died, I shed a few tears, but not much. They were ill and very old. I think I would for a younger person, but thank God haven't had to experience that yet.
But one thing that brings the tears suddenly pouring out is reading history things about WW2 where my Dad was involved. Maybe it's all been suppressed since those days (I was alive and quite aware at the time.)
Do you cry easily?
What to do with immigrants? - ask Shakespeare
Reducing contact because my heart just isn't in it.
"Old fashioned" expressions that young people have never heard.

One day you may find the tears flow at some unexpected stimulus but even if they don't, you know yourself that your dear parents and daughters were loved.
