No I'm not talking about knowing your salad fork from your entree fork (fyi: salad forks have longer tines and entree forks are smaller). I'm talking about manners that affect others. While all etiquette rules are so that respect is shown for others (and you are saved from embarasssment), let's face it, in our modern times no one really cares if you don't pass food to the right (counterclockwise) at a table, open the napkin in your lap, or make sure the knife's sharp edge is facing into the bowl/plate and not towards a person (yes all of the mentioned are proper etiquette). What I'm speaking to is the inconsiderate nature of those around us. People that purport to care for you (or at least show an interest in you) blow you off, cancel plans continually, will not respond to invitations (Facebook events anyone?), etc. What a unique way of showing you care!
Manners may be 'old school' to some, but hey, I'm young and I refuse to explain away bad behavior by contributing it to a paradigm shift. Let me also add that the teller/cashier/barista being rude is one thing but when someone you have a relationship with does so, draw the line!
"Manners are a sensitive awareness of the feelings of others. If you have that awareness, you have good manners, no matter what fork you use."
