@GreenLantern53 - can you tell us, please, why you aren't going to the Parents' Evening - in general terms.
Do you have a previous appointment or vital medical appointment/interview? Some prior arrangement that cannot be changed? If any of these are the case, there is no reason why you couldn't say that to your child's teacher, without going into any detail, and I am sure she would have been willing to organise to speak to you another time.
Or is there some practical difficulty - childcare for your dd, perhaps? If so, rest assured you will not be the first parent who has that problem, and the teacher will be able to suggest a solution - perhaps your child could sit in the Reading Corner with a book whilst you and the teacher talk. Or maybe they will be accustomed to having the children there.
As I have said before, I can't think of any valid reason for missing Parents' Evening that couldn't be mentioned in general terms. Just saying you can't go, and not giving a reason, gives the impression that you don't care enough to go - both on here and to the teacher - and I am sure you don't want to do that.
