Correct Electron Pushing with HCl and Water My book indicates that the following electron pushing is wrong:



So what would the right electron pushing diagram be? 

I have the following in mind. My rationale is:

1) Electrons attack protons, not the other way around. This is just convention right? Is this just a conceit in chemistry; just a standardization? On a related note is this why one person described organic chemistry as:

"The foundation of every reaction in organic chemistry can be found in one statement: Nucleophile Attacks Electrophile."

Rather than electrophile attacks nucleophile? 

2) Water is the base here; water is the Lewis Base (nucleophile) so water will attack the hydrogen cation (which is a bare nucleus).
3) HCl is the acid here; H+ is the Lewis Acid (electrophile, so it's going to go toward the lone pairs on the water). 

So:

Would this be right?
1) Nucleophiles often have excess electron density while electrophiles are characterized by a lack thereof. The electrons flow in the direction of lower electron density (and not the other way around), because they are "attracted" by the positive partial or formal charge of the electrophile. This is the reason why the first scheme from your book is wrong, because it shows a nucleophile attacking another nucleophile.

2), 3) and the reaction scheme you have drawn are correct.
