Why does everything you touch fall apart?

Physics: The subatomic particles that you possess interact with other subatomic particles, causing substances to break apart with new ones forming as a result.
Psychology/Human Behaviour: It because you are looking for the things that fall apart. To be honest, not everything you touch falls apart, but your brain has gotten very good and observing the things that do, and you neglect the things that do not fall apart.

A lot of things would have fallen apart even if you were not there, but you now somehow infer that your presence is significant in it falling apart. This is a false assumption, but understandable given your observational pattern.

A lot of it has to do with patience and effort. Many things take a lot of energy and effort to keep together. Perhaps you do not wish to put in the effort, or are afraid of trying and failing, so would rather not try and fail to save the effort. You could just be lazy, or you could be busying yourself with other things that may or may not be as important.

It could also be that the way you are constructing the things that fall apart is flawed in some way. Perhaps you are not creating some part of the foundation when you set these things up, so that the natural order of it is to fall apart unless great effort is expended.
