I say hello or good morning, etc to people in the village, wouldn't do it in town - people might think I was a bit of loon. When the things were little I had a smile practically glued to my face the whole time as twins attract a lot of attention (even without all the other little peeps) - must have looked bonkers!
I think i'm smiling but I don't think my smiles are very..... smiley....
People usually say I look pissed off or angry. I get "yir face is trippin yi!" a lot and my old manager in the 'drug said I had a "sour pus" :-)
People that have a constant grin on their face give me the creeps. I just generally don't like over happy people. They annoy me. I'm a pessimist at heart! :-)
