Another reason why Snape hates Neville too?
As you may well know, Neville was born the day before Harry, so it was as the 7th month ended and all that, but if Voldemort tried to kill him instead, would it have made a difference seeing that Neville is pure-blood not a half-blood?
'He [the eavesdropper] only heard the beginning, the part foretelling the birth of a boy in July to parents who had thrice defied Voldemort. Consequently, he could not warn his master that to attack you would be to risk transferring power to you.'
Now I am probably wrong as my memory is rusty, but this was taken from the JK site, and was the eavesdropper Snape? Who then realised that Voldemort messed up trying to kill Harry, thought he wouldn't have messed up trying to kill Neville instead, which is why Snape hates Neville?
