I used to be like Microwave and return rudeness or disrespect and then, like you, painretreat, I decided I wasn't going to waste the time nor energy to get angry because as you pointed out, it's a way of letting "them", control you. If they "make" you angry, then they're controlling you. Rise above the pettiness and repay disrespect with respect, not only does it usually freak 'em out, but a lot of times it makes them see or realize their immaturity. Then they wanna be friends and find out how you do it.
After they find out I've been a martial artist for many years, since I was a teen, (I usually don't tell anyone) and when I get the opportunity to teach them a thing or two about themselves and how to better be in real control of yourself, instead of simply believing yourself to be in control when really you're not. The philosophy of peace and working together in unity almost always accomplishes more than the individual by themselves. :thumbsup:
