It's bad to chicken out at the last minute.
Amanda is supposed to go to her doctor's appointment to get the results of a test.
Amanda wants to decide if she will enter the building.
Amanda heads right in to see her doctor and find out the results.
Amanda runs away at the last minute because she's afraid of the possible news.
It turns out the test result is negative thus she isn't sick at all.
Now it takes her much longer to find out, and she panics for much longer.
