Why so many handbag purchases have to be validated by this forum?

I am amazed by the amount of people seeking for validation for their purchases from this forum. Only you can tell whether your purchase fulfills your needs etc. It seems to be very common to seek validation from this forum for your purchases and I don´t understand why. I have bought dozens of bags during my lifetime and never have I seeked a validation from someone else for my purchases. I feel if you have to seek for validation your are not happy with your purchase from the first place and need to convince yourself to buy the bag. Please make me understand: are you so insecure that you need a validation from outside or do you want to see what´s trendy and possibly ”earn money” from your purchases?
