@Region Philbis,
Ted Cruz thinks going to Cancun "was a mistake in hindsight".
How many of these hindsight mistakes will he regret in his career?
This is the kind of regret like, "God forgive me but I had a great time doing it."
"I cheated the American people but I got rich in the process."
Do you think there is any real regret here?
BTW goats are called "hinds" in the Bible...
It is surmised that the meaning here is, goats have an inability to look back.
