Yes, we do have fun ...we happy band!
My husband walks our bigger dog every morning and he's always been surprised at how many miserable people there are ..he'll often smile or say good morning, and they just walk on.
Only two weeks ago, I picked something up in the supermarket and was amazed at the price of it ..made a remark along those lines to the chap browsing next to me, and he totally blanked me! It made me cross and I felt like saying something like 'Hell, did I grow horns or something?' ...but thought better of it ..after giving him a Paddington Bear stare!
Most of our neighbours are out at work every day and are out and about most weekends, but they're all pleasant. In fact we avoid one chap who lives nearby because he's a darn pest! Younger than us, but not married, no girlfriend, no nothing apart from his job, so he's a bit too needy! Couldn't seem to get the fact that I actually work at home and cannot cope with people constantly coming to natter whenever they feel like it! Grr! In his case I had to break with my usual peaceful self and get firm with him!
True, some people do have the weight of the world on their shoulders, but for the most part, people seem to have insulated themselves and become morose. They lost the plot (if they ever had it!) when it comes to smiling and considering their fellow human beings!
Never mind, there's still some pleasant people around!

....I'll get back to my birds nest liquid ...still picking bugs out of it!
