You obviously have a personal issue with me here anyway, so lets try and put that aside for the sake of this discussion, shall we?
I also wear band t-shirts because I like the bands. Many I have seen live, some were sadly, before my time but that doesn't mean I can't appreciate them. I don't think you have to have seen a band live to be a fan.
I don't think it is sad or shallow, TBH. Do other people dress their children in different 'styles' to themselves? Why? Surely if the shops that you normally go to for your own clothing have childrens clothes, you will buy them from there?
There are a few lentil-weaver type families at my sons nursery - their children dress in similar clothes to them. There are some WAG types, their children tend to wear designer style clothing, there are some Boden-type mummies, their children wear Boden-type clothes.. I didn't think that dressing your children in keeping with your own 'family style' was sad or shallow, I thought it was normal.
Do you dress wildly differently to your children?
FWIW I have never said taking drugs is 'cool'. Nothing of the sort.
