standard model - Why do quarks have a fractional charge?


I am aware that evidence exists that strongly suggests the existence of quarks and do not doubt it. It is just simply really weird to me that they can have a fractional charge. While other elementary particles, such as the electron, carry an integer charge. So logically I would expect charge to be made up in discrete packets of charge just like energy is made up of discrete packets of energy called photons. And spin in particles comes in integers for particles as well. So it's just really weird to comprehend that in this one instance a subatomic particle has fractional charges.


Does this mean you can break up all other integer values assigned to other particles or subatomic particles? Or is this just a freak of nature and only happens in this one instance?


If I'm not being specific enough please try your best to answer what you think I'm asking and if need be I do not mind further enlightening what I am thinking about since I do not fully comprehend the standard theory of particles as I majored in a branch of physics considering general relativity and the universe on a whole.


Thank you if you can answer in the least technical answer possible.
