Consider the following conversation:
"I need to go to the time machine first before we go."
"Um, okay Julia, you sci-fi weirdo."
"How is that weird? Or even science-fiction?"
"Time machines don't exist."
"Yes they do!"
"No they don't!"
"Then where else am I supposed to get my money from?"
"Time machines are at the bank. You've never heard of one before?"
"Only from H.G. Wells."
"No, no, not TIME machine, TYME machine. You know, Take Your Money Everywhere?"
"Never heard of it."
After several phone calls to prove I wasn't off my rocker we finally did a drive by so the proof could be tangible. Because I do know time machines don't exist. But teleportation on the other hand... well, that's a different story.
