it always turns out to be fun.

I'm sure it is like that:)

So here's another example:

My father used to say that it's more fun to listen to songs broadcasted through the radio. The element of surprise is there, which is killed by the cassette player. Though we listened on both, he would mention this fact when his favorite song played on the radio out of blue.

So yes, too much planning kills the joy and element of surprise...
