OP, I think you said it all right there. Usually things work out JUST FINE. And as a single-parent, what choice do you have? You have to work and so you do your best.
Life isn't perfect -- for you, me, our children, anyone. There are always going to be mixups, difficulties, snafus. We all have to learn to cope and accept the ups and downs of life. It's reality.
I'm sure you're doing the best job you can for your family.

For those who were jumping all over the poster who commented about not dropping the ball on your kid. I'm going to back her up a bit. Not in regard to the OP -- but our society in general. I feel that so many kids are getting the short end of the parenting stick. It's sad that we've reached a point where most families feel the need for both parents to work. I really long for the days when there was one parent at home -- for the sake of the kids and for the family, in general. Politicians are now proposing lengthening the school day by three hours in order to cover that "at-risk" time for kids -- the time between school letting out and their parents getting home from work. I think it's just sad we're putting this burden on our kids. Kids getting shipped off to daycare or placed with nannies as infants, extending the school day so that they be supervised properly because parents aren't there. I'm concerned about how this will impact children. So I do share some sentiments of the unpopular PP. If that makes me unpopular, too, then I can't help that, because that's the way I feel.
