It's more like I want to go to the store, so I invite the store to send me a driver who will use my car to drive me to the store. The store accepts my invitation, but when the driver shows up he wants to invite a bunch of hitchhikers into my car but I politely decline. Meanwhile, I'm driven to the store.
Your bus analogy assumes that Facebook owns and operates my browser. That is incorrect.
But like I said. Analogies get really dumb when you get too deeply into them.
