I will start with the short version of the answer and then move to a little longer version of it.
We do not observe quantum behavior in real life because of the
limitations of our biological architecture.
A little longer version
We didn't need to have evolutionary traits that are attuned to quantum phenomena. It is the reason why quantum physics seems so queer. An untrained person doesn't have a vocabulary to express the phenomena of an object being in two opposite states at the same time.
For example, a quantum coin could be in a state of both head and tail. How is that possible? How can it be? Well, our tongues can't articulate it. In fact, this whole thing about light being both wave and particle is a hype. This is used like a catchphrase, but all it shows that we don't have a large enough vocabulary to describe the nature of light and other quantum objects. And that's okay! In real life, we catch a ball and not an electron.
That's why, in real life, quantum phenomena is not observed.
Just because it's not observed, doesn't mean it doesn't occur
@Jon Custer, mentioned about laser in the comments, and I'll mention that here too. Every time you are in a presentation, and the presenter uses the laser pointer, quantum phenomena is occurring. Sun shines, and the explanation of the mechanism needs quantum physics. We have food because of photosynthesis, and that's a quantum phenomenon too. You observe quantum phenomena all the time, if you define observing by both sensing the event and acknowledging the mechanism behind it.
The last thing I'll comment on in this answer, is the "associated wave with a particle" thing that you mentioned in the question. There's this fundamental constant in quantum physics, called the Planck's constant, $\hbar$. I could write down its value and then tell you how disastrously small it is. I won't do that because, $\hbar$ is a constant with physical units. You can say 2 is a small number. But, you cannot say 2 m is small, because it's a large distance for an ant, and small distance for an athlete.
As far as the $\hbar$ is concerned, we're giants compared to it. By 'we', I mean our coarse senses. Again, $\hbar$ isn't small, our senses are accustomed to too large of things!
