I was at a met yesterday and their were two things that I never heard before, both by mothers to their daughters.
The first was the mother shouting to her daughter, DON'T DIE, DO NOT DIE (just the imaginary a runner needs to hear toward the end of a race)
The second was even more ridiculous. A mother is running along side her exhausted daughter yelling, "RUN FASTER, I'm running as fast as you and I'm terrible"
You can't make this stuff up.
