Don’t you hate it when people cut in line? The other day, I was driving and someone cut in front of me and they made the light before it turned red and I didn’t. Enter our daf:

With regard to two people who purchased a cow and its offspring, where each purchased one of the animals, whoever purchased his animal first shall slaughter it first, and the second one must wait until the next day to slaughter his animal, so as not to violate the prohibition of: It and its offspring. But if the second one preceded him and slaughtered his animal first, he benefitted, and the one who purchased the animal first may not slaughter it until the next day.

So, the law is that the first purchaser gets to eat steak that night. But, if the second guy is a jerk? Well, then too bad.

Such is life. Jerks often hurt others on the way to make life easier for themselves – but just because they get their way does not make them likable, or ethical, people.
