Some parents blamed their work schedule. Others whined that they deserved to have a social life and go on dates. This is ridiculous. If an adult makes a decision to have a child, they must take all of the responsibility that comes with parenthood. It is certainly not an easy job, but it is one that must be taken seriously.
Work is never an excuse.
If work takes so much responsibility and time that your child will suffer, don't become a parent. If you have to leave work so early every morning that you leave your child standing alongside the road alone waiting for a bus, don't become a parent. If you have to leave elementary, middle and even early high school age children alone in the afternoons, don't become a parent. Parenthood is a choice and it is a choice that some people don't need to be making. And it's not too late for those people who are already parents.
