1. It's usually a very heartwrenching situation. I've always considered my 76 year old father a macho/ tough guy; ex-military, retired law officer, etc.....he never cried and didn't tolerate me crying as I grew up. I've only seen my dad cry 3 or 4 times during my life; after mom died in 1977 being the first...and he acted like it embarrassed him afterwords to show such emotion (he bawled 25 - 30 minutes; ironically,that was the only time I ever saw him cry over mom's death, and it happened three days after her funeral; he kept it all bottled up inside until then).
2. There have been many times during my life when I wanted to cry but fought to maintain my composure; not neccesarily because it was "lame", but just not wanting to upset others or portray that image of myself in public. I'm a cancer survivor, and have lost quite a few young friends to the disease in recent years (many whom I met because of my illness and/ or Relay For Life). Last fall, I lost one of my best friends to leukemia; only 39 years old. I knew she was dying....would manage to remain cheery/ hold it inside until leaving the hospital, then cry all the way home. I did the same at her memorial service....kept it inside until reaching my truck, then the tears flowed. It wasn't as much trying to be "macho", but didn't want to break down in front of her husband, their two little girls, family....knowing they were already anguished and trying to be brave.
I don't cry often, but admit I cry much more often now than two or three decades ago. Most of the time, it's due to losing someone I love (dying) or watching them suffer; sometimes though, even a happy occasion can bring tears to my eyes; watching my young nieces & nephews excitedly opening their presents on Christmas morning, etc.....just from feeling so blessed to still be alive and with my family
