Please never judge someone as heartless when you don't see them cry. I positively couldn't cry for decades, and many of yall here on JWD know some of what I've gone thru. Sometimes a person goes thru many trying times and tragedies that seem to snowball and there just doesn't seem to be a private place and time to give in to the grief, so it's tucked away and set aside time after time in order to function and do the necessary things for the other people a person may be responsible for or for any number of reasons. Then one day that huge dam that's been built upon and built upon becomes a huge burden. And the least little thing may be the start of a crack in that dam, for which one had better go out and buy stock in Kleenex.
Feeling pain and grief often manifests itself in different ways in different people. Some become hostile, or mean. They will lash out to inflict unwarranted pain on others, but it's just a manifestation of the pain they themselves are feeling. Some laugh seemingly inappropriately. Laughter is like a "vent"....letting off some of the pressure from grief and personal pain.
Please don't ever judge others for the way they manage to deal with their personal grief and pain. You never know what can happen in your life from one day to the next, and life can be so unfair and tumultuous. And some dams can take more pressure than others.
