Watching Lee Morris play in 1998 and remembering his dad Colin playing down the wing for us (I hope Colin Morris doesn't have any footballing grandchildren, I couldn't cope with watching three generations of the Morris family play for us!).
Secondly was realising I would never see a United player older than me play again (I think it was Gary Speed - my name gives away my age!).
There hasn't yet been a United manager younger than me, I'm hoping Wilder will stay for years to come, partly for that reason!
