Andrew:
The Muggle couple, Mr & Mrs Evans allowing their younger daughter to
attend Hogwarts School of Witchcraft and Wizardry?

Lily Evans deciding to date James Potter?

Voldemort's decision to go to Godric's Hollow at Hallowe'en in 1981
rather than the Longbottom's house, (thus choosing Harry over
Neville)?  Harry himself ponders this point - can't remember where
though!
