I was walking up the steps of the church the other night when I saw a woman walking a dog. So I smiled and said "Your dog just looks so happy!"
She took out her headphones and said "What?"
"Your dog looks very happy--what's its name?"
"Oh that's Nova; she's six months old--'
"Wow, she's happy--" (Meanwhile Nova was so happy she was play-biting my hand and my sleeve and one of her owner's headphones.) "Is she a bulldog?" I had to ask as I am not very familiar with bulldogs.
"Yes -- Blue Nose pit-bull; and we just got her not long ago--"
"Well she's cute." And we hung out for a few moments talking about dogs, raising pups, and playing with a very attention-hogging Nova.
I'm not only white but I "dress white." It was hard to get more stereotypically "white-person" than me going up the steps of a Roman Catholic church in Connecticut dressed in Harris tweeds, a cream-colored sweater, a brown necktie, and a pair of Confederate army trousers. On top of that I have a trace of a Southern accent, at least enough to get a ton of weird questions about "where are you really from?"
And it's hard to get more cool-modern-diverse than what this young African-American lady was wearing, which was all kinds of colorful jackets and generally a very proper sort of modern walking outfit. She had shaved off most of her hair and dyed the remainder a trifle lighter than her skin. A rather cool combination though she'll want a nice hat when the snow starts to fly. We aren't from the same subcultures but all you really need is a bit of a shared interest and the ability to just throw aside the worries and be open. Most folks are super friendly and want to share their own interests.
I missed her name as I didn't want to pry (or miss Mass) but I guarantee you that a few minutes of chatting later I could've probably asked for her telephone number and likely gotten it. Basically just go for it. I don't look at social interaction as a win- or -lose game but as experiences in a life, and it was nice to meet another happy person walking a happy dog on a nice Sunday evening.
