Nah...life has too much to savour for me to waste time & energy cultivating negative emotions.
I've long ago acknowledged there are just rude, & discourteous people out there. {shrug}
Such types are completely unworthy of the energy that would be fed to them. C'é la vie.
I can have a good day, ...or I can work myself into such a state that I end up having a bad one.
It's mine to decide, ...and ruining a perfectly good day over some socially ignorant fool who was obviously raised in a barn is NOT how I choose to go.
