A normal person likely never reads any of the "fine print" for the product & services that she buys. Terms of condition, liabilities, obligations, indemnification, rights & permissions - these are all concepts that most of us unwittingly agree to when we click through a website or sign a waiver form for new merchandise.
Lucky for me that I get to spend some time occasionally drafting such agreements - and figuring out exactly what we sign up for without really knowing. Crazy stuff, to be sure, these contracts. All I can say is think twice before you sign off or click through the next legalese - you might not realize what you have just done!
