This evening I rode my bike around town and waved at anybody who would look at me. Many waved back. Some wouldn't even look at me. Some looked straight at me and did nothing. That made me laugh. Finally as I was coming home one of the town's few(besides me) longhaired hippie looking types walked past me. I have said hello to him before and usually he just acts like I am the scum of the earth. Today he was stiffly ignoring me. Just as I passed by him I yelled out "Hi!" and he actually turned and said hello to me quite civilly. Do you say hi to strangers? What kind of reactions do you get?
