I'm the opposite...I rarely get excited. It gets on people's nerves or upsets them sometimes, like when I receive presents or something I just
cannot show much emotion or get excited. Once my parents surprised me with a car and I still didn't feel very excited. The only time I got really, really excited was on Christmas morning when they told me I was getting a horse

I was about ten years old. I get excited about stuff like ordering something that's coming in the mail, but it manifests more like anxiety...obsessing over when it will arrive.
I think I am like this for the most part. Even when I am given something I genuinely like, I do not get excited. I think "I wanted this. Now I can *insert activity which requires previously wanted item*."
Often, people are displeased by my reaction or lack thereof.
I do not naturally show any emotion when other people are excited either. Lately, I have been trying to fake some excitement when other people tell me things they are excited about. I have always found the "awe" sound people make at the happening of happy events to be extremely annoying; however, I tried it when one of my friends told me she was pregnant and when another told me she was getting married. I am afraid it came out more like the Grandma-just-died sort of "awe" though.
