Making people happy...!
...the nuances of social interactions...
Anything involving Mathmatics! It was never my strong point and never will be!
Marriage. I'm dead after all.
Making chocolate chip cookies. I have no idea why, I just cannot make them at all!
Balancing my accounts.
Cooking. It's unfortunate that I never learned the basic science of cooking (whether to boil or broil or bake a thing). I can make only good salads, burritos, and omelettes.
Also, I would say reading music. I can feel very well what music can/should do, but I was never able to equate dots between lines on paper with sound.
listening to heavy and emotional speeches/topics...tears me up, dude! I speak and laugh hard, am that type of a person whos tears are just around the corner, not that far ...;-)
orders of others when some one impose their work on me
