Have you supported Man Utd all your life then?
Yup, since I was 5, my mum was an Man U fan (my dad being from north London supported Arsenal) and she used to work United in marketing/sales, she met 3 Utd managers while she was there (Big Ron and Fergie, I think the other was Dave Sexton, can't remember off top off my head, she left in 94'.
Had lots of signed united shirts/boots/scarves/footballs when I was younger (From 83' to 94'), they were all auctioned off for the charity for the condition that my mate died of in 95'.
I distinctly remember most of my mates at school supporting Liverpool and Tottenham (Glory seekers you call it today!), they don't bother giving me grief about being a "Glory Seeking" United fan as they know I was supporting them when they were an average team in the 1st division when I was younger, also being from Manchester helped!
