Obviously, you can never reach the wall because you can subdivide the
remaining distance to it in half infinitely. Naturally, it follows that
you are infintely adding increments of distance to that already travelled.
This will, eventually, result in travelling an infinite distance. This is
all very tiring. There is also the mental strain of dealing with the
proposition of an infinite distance yet to go. You are actually dropping
of sheer exhaustion about half way to the wall.

Lively discussion then ensues...

You should direct some of your less gifted students to leave the classroom
and come here. This will have the salutary effect of raising the IQ in
both places.

Unfortunately, by your logic, they can't get here either. :-(
