I am the type of person who wants everyone to be happy with me. So, when someone exhibits displeasure with me, I take it personally and work hard to rectify the situation. One example is when getting honked at. It really ticks me off when people honk at me- especially when there is no reason for it. I was at a car garage, waiting for the machine to print off my parking stub/ticket, and the car behind me honks! I tried to hurry and get out of everyone's way, but was rather perturbed by my lack of control and his impatience. That experience put a bit of irritation in my otherwise pleasant day.
When these people act this way, it really affects my day. I don't try to take it personally, but rudeness is always hard to swallow. I know it's not always stemmed from my workplace. It comes from their workplace. I always try to be polite to them so they can have a bright spot in their day. I know I always remember a smiling face when at the store or a resaurant.
Think about when you are going through your day. When do you get upset with those around you? Place yourself in their shoes and think how you would feel. Then purpose to be cheerful. It takes effort sometimes, but is well worth it. You never know how your politeness could boost up those around you.
