Special Occassion?

Yesterday, I had the same thing happen to me about three times. I spilled a ton of water into my lap twice. Then the little boy that I was babysitting accidentaly dumped ice water all over his face. These were all really funny, but I was wondering...why is it that things like this all happen really close to each other?
The first reason that these things probably happen is that they fit the mood that we are in. Sometimes when things happen to us, they happen due to how we feel or act. If we stay in the same mood throughout the day the same results may come more than once throughout the day.
Secondly, we're paranoid that we'll make the same mistake again. Not only does this increase my likeliness of having it happen again, it makes it a bigger deal the second time that it comes. It can get ridiculous when it happens three times during the day. (It's a good thing that I was in a good mood and that Mr. Rich made it so funny.)
Finally, when we do something, there is usually an effect or result to what we do. Sometimes, as the song says, "one thing leads to another." The things that we do or have happen cause more occurences of a similar nature to follow. It gets crazy, but it can be funny (especially if it's a waterfall of ice-cold water pouring into my lap or onto the face of my neighbor.
Sometimes, these repetitions aren't desirable. However, they can be humorous. Either way, the chain-reactions are usually caused by the mood, paranoia, and "one thing leads to another" concept. That' s my interpretation anyway. Haha.
