Regardless of how many times we hear the idiom "don't judge a book by its cover," it's still pretty common to make assumptions about people's lifestyles and emotional patterns based on how they look or who they hang out with.
The Hell's Angels came to my uncle's funeral. What's the nicest thing you've seen a gang do?
OP encouraged others to share the nicest things they've seen gangs members or seemingly tough people do, as a way to break some of the misconceptions.
My mom had four older brothers. One I've only met once, because he lives in Florida and that's halfway across the country. Growing up, the other three all lived in my hometown, and I saw two of them pretty regularly. The other uncle - Dewey - only came around when he really needed something.
Dewey was a good ol' boy born into a family of staunch whitebread catholics. Dewey was completely bald, with a mustache/goatee combo that would make Jamie Hyneman jealous, and mirrored sunglasses that never left his face. Dewey liked his smoking and his drinking and his f*cking and his motorcycle. Dewey and my grandfather - a WWII vet who drove himself to the hospital when he was having a heart attack because "ambulances are too expensive and will wake up the neighbors" - never got along. Dewey was a wild child: married by 21, kid by 23, divorced by 25.
