I wonder why...

I wonder why I always hold it when I have to go potty and I hold it until it is an emergency...especially when I am on the computer and then I rush and am uncomfortable. It is really weird. I am doing it right now and that is why I decided to write a blog at that moment in a rush to finish before the emergency was at my "door". Most of my friends know that I do this and they can not understand it but they laugh at me.
I also have a sudden urge to go when I am doing one or more of certain things such as 1. looking at greeting cards in the store, 2. browsing at the bookstore, 3. when I get phone calls from my friends, and 4. when I get on the computer. It is very strange and I have tried to come up with real reasons why but I have to admit I am just B.S.ing the reasons and can't really figure it out. I usually curb this feeling in a number of ways like pacing back and forth, shaking my legs, "clenching" (LOL) and so on. I am not really sure why the ONE way that avoid handling this issue is the only way that will solve the issue which would be going to the restroom and stopping this whole process all together. But I guess all of my friends would be lacking one thing to laugh at...and needless to say the emergency has caused more than a few "accidents" as many of you already know.
