"So, yeah, I think I am rude in some regards because I fall victim to the notion that when I'm in a hurry I can dispense with civility."
It truly drives me up the wall when employees of the store I'm shopping at will do this. I remember that they used to go out of their way for customers and now if they are in a hurry they will literally plow you down.
Our dog bit my husband this year. Basically he doesn't like people in his space. We've learned to deal with it in different ways but it scares me when he's around people he does not know. So, when I had a party I asked my vet to give me a sedative for him to take the edge off. All it seemed to do for him was make it difficult for him to walk for a day or so. I'll never ask my vet for those pills again. Now when company comes over I get him a big ol bone and keep him in his crate.
