The kindness that is my weakness

For as far back as I can remember I have always been described as nice, sweet kind etc. Now this would be all well and good if people actually treated one the way they were treated!
I have the uncanny ability to find the biggest A-holes who take kindness for weakness and friendliness for naivety!!
You know the kind little old lady that you offer to help her push her grocery cart to her car and she not only asks you to load her car but can you please place the heavy stuff on the bottom and watch her eggs because she wants all twelve when she gets home!
Then there's the boss who talks crazy to you because you have enough home training to address him as sir unlike the rest of your fellow employees who address him as "informally" as possible If they even address him or acknowledge him addressing them!!
My personal favorite are the disrespectful people (and you know who you are) who think that just because they breathe oxygen means the rest of the world are supposed to cater to their whims no matter how ridiculous the request is. for example I had a Perfect stranger see me at a gas station and ask me if I could give her a ride. When I ask her to what location she gets an attitude like I asked her for the ride and snaps "Well if that much of a problem, I'll just walk!" Now any normal person would have gotten in her car and said "cool I guess that problem is solved!" Not my dumb butt I say "Well where are you trying to go?" She replies "just up the street" I quickly let guilt take over and tell her to jump in and I'll get her to where she needs to go. She is Right, it is right up the street, at least after you get off of 94 jump on 35 south drive about 20 minutes exit onto France ave and drive up the street 6 more blocks!!! By this time I have used up the $20.00 worth of gas I had just pumpehd, I'm late picking up the kids from school and my Sweetie is on the phone with the FBI thinking I've been surely kidnapped! My passenger however skips out of the car without as much as a thank you!
Someday I am going to learn the art of no and be a professional A-hole myself but until then, what can I do for you today??
