In a pinch, you need to make use of what you have. Substitute yogurt
for mayo, use blush as eye shadow and have sex with the Latino boy who
was making oral sex hand gestures to you on the train instead of waiting
for Mr. Right, the disease-free Ivy League grad who probably doesn't
even exist.
In the long run, using what you've got really saves time, even if it
makes you look sloppy or Godless.
