If someone tells you to walk 1,000 miles to get somewhere you need to be, would you really respond with anything except "I can't"? It's an acceptable shortening

If someone tells you to walk 1,000 miles to get somewhere you need to be, would you really respond with anything except "I can't"? It's an acceptable shortening of "well that's a really long way, and it's really hot, and it would take a long time, and I don't have that kind of time, and I'm not in very good shape, and my knees are bad"
