Ugh! I can\'t stand it when people celebrate an "N month" anniversary when you can\'t have an "N month" anniversary! People need to stop worrying about the petty things. Girls need to stop giving guys so much grief about celebrating a month or three months together.
To make up for whatever sadness she\'s going through, take her out to dinner, buy her something that she has had her eye on for a long time, get her a belated anniversary card (if they make those), take her to some place memorable (build-a-bear workshop, the oceanside, whatever\'s local). Dress up if you have to.
But really, I don\'t think she should have a cow over such a petty thing.
