Don't be mean. I promise to do my best to judge that fairly.

I like the imagery of the last post because it was tapping into the idea of waves and how sub-atomic particles behave like waves.
However, erm actually ๐ค ...
No, they don't overlap. Electrons are negatively charged, and like repels like. The orbitals will repel each other. This repulsion is the reason why you can feel the fur.
Edit: I'm getting nay-sayers that reckon they do. Please provide a reference that explains inter-molecular orbitals that cause bonding for a hand touching fur. The only thing I can think of this happening is for transition states. This would require a chemical reaction. I don't think we categorise "touch" under "requiring a chemical reaction".

I'll write an explanation here, but I'll try to answer all questions from the thread. Also quantum mechanics is complicated, so sorry for the long text.
Electron orbitals are weird and complicated, for hydrogen we can solve them analytically and depending on the quantum number of the energy levels we are looking at, they take the forms as in the picture on Wikipedia:

Now whatever energy levels and quantum numbers are, what we are seeing is the probability of the location of the outer most electron (ok hydrogen only has one).
To understand bonds, we don't really need the picture of orbitals, but what's important is understanding that electrons occupy shells. A certain number of atoms can fit into a shell and when it's full, the electrons start a new shell. It gets complicated quickly with more electrons, however in the simpler case, a shell can fit 2n^2 electrons, where n is the shell number. So for n=1, a maximum of 2 electrons can fit, for n=2, a maximum of 8 electrons can fit.
Shells want to be filled, so that leads to two possible bond types. If an atom with a free electron comes close to an atom that has a free spot for an electron, the electron can hop over to the other atom, at which point we have an ionic bond (the atom that loses the electron loses one electric charge and is thus positively charged, the other atoms gains an electric charge and is then negatively charged, so they want to be together).
Another option is covalent bonding, where instead of an electron jumping to another atom, the atoms actually share the electron.
Now do orbitals overlap? I wouldn't give that question a yes or no, because, at that level, we can't really separate atoms anymore. When the atoms are far apart we can draw separate orbitals for both, but when they get together, new orbitals form that is the solution of the electronic configuration of the new molecule we just created. It's more like the orbitals that we have get deformed into new orbitals.
Is it electrons travelling in your brain that made you think that?
I have read about solipsism but I refuse to believe information I gathered from materials made from quarks and gluons, transported to my body via photons
