When will we laugh?

When relating laughter to time, it is easy to overlook all those times that we're being exposed to a funny situation yet don't know when we actually are going to laugh. Usually, we laugh in situations that we know are going to be funny or are supposed to be funny, but we all know there are those times where we are expecting something funny and are completely let down. This is different from the obligatory laughter I referenced in my first post because in these situations, we continue to wait for the moment in which we are expected to laugh but it never comes. Because this moment is inevitably awkward for both people involved, we are forced to act as though we didn't know the moment was building up to be something "funny." However, when we resort to this, the person in charge of the "funny" moment is disappointed in that we weren't able to find the funny time to laugh. Timing our laughter is both voluntary and involuntary. In these moments I talk about above, the timing of our laughter works hand in hand with the build up that comes with it. We think we are timing our laughter voluntarily, for when the funny moment comes, however are let down in realizing that there is no funny moment. Our involuntary laughter occurs when we least expect things to be funny. These are the purely true moments that we find funny, resulting in us to laugh whether we planned on it or not. A shift can also occur from voluntary laughter to involuntary laughter. When we think something is going to be funny and we are planning out our laughter for the exact moment it should occur, something else might happen that we burst out laughing because we weren't expecting it, resulting in our involuntary laughter.
