I realized that because I am such a giving person, that I expect others to do the same and get angry when they don't. Now this is definitely something I need to work on. But just because I go out of my way to do little acts of service for others, doesn't mean they have to...I shouldn't expect that from others, right? WRONG. Now, I should not get angry or upset if my expectations are not met, but I also should definitely not stop expecting people to show common courtesies and maybe a little more than that. I guess my challenge is this: expect greatness. Not only in others, but in yourself. Hold yourself to higher standards. Go out of your way to pick up that little piece of trash, to fold your roommates laundry, to bring a friend some coffee when they're having a rough day at work. Being busy is not an excuse. If you are too busy to do something nice for someone, than you're too busy.
and you'd be surprised how much joy that can bring. Do unto others as you would have them do unto you.
"Do small things with great love"...
I also have a challenge for myself and anyone else having similar struggles: any time I get angry about one of the above stupidities, I am going to do one act of service to counteract that. BUT, I need to make sure I am not doing it out of resentment, otherwise it is meaningless.
Pray for opportunities to love and be loved. Be the change you want to see in the world!
