Settling disputes with your word
Made a deal with my neighbor on a property line issue. No lawyers, no paperwork, just our word and a handshake. His dad did the same thing with my dad 30 years ago. That's how you operate as a gentleman. You don't need contracts and courts if both men have honor. Seems like this is a dying concept though.
That handshake means way more than any contract ever could. Your kids are watching you do business the right way and that's gold.
