confusing IMHO. Code becomes cleaner and easier to write and read
when you become familiar with classes.

If I have to write a class just to create
one instance of it & call the main() method, I might as well use Java!

I'm no fan of Java. But it's not about a "main" method, it's about
sharing data between functions. Most of the time non-constant globals
are a mistake. If the data can't be passed as an argument, then it
should probably be part of the instance data of some class. Which class
is a design decision, and unlike Java, I wouldn't encourage writing a
class for unrelated functions, just to bundle them together.
Anyway, back to your problem. Since your code doesn't have threads, it
must have an event loop somewhere. Event loops don't coexist at all
well with calls to sleep().
while waiting:
time.sleep(1)
If you start that code with waiting being true, it will never terminate.
I don't know turtle graphics, but if it's got an event loop, then you
can't write your program procedurally. A function called
"wait_for_click()" is nonsensical.
