That's even worse. I was giving them more credit but maybe you're right. The wedding industry thrives by sowing the idea of a perfect and unique wedding into the minds of little girls and later some man will come along and fulfil that dream.
I wouldn't buy dolls, and after, their clothing either. Yet my daugthers love them and I love my daugthers. I wouldn't buy expensive jewelry, yet my wife loves it everyday still.
There is so much you wouldn't do for yourself but do for the ones you love. That doesn't make it insane or just to not disappoint. You do it because it makes you happy to see them happy. If you would do the same if you were alone is not the thing that matters here.
