My neighbor was telling me it would be a trip hazard.
Why is your neighbor telling you about a trip hazard?
I was planning to drop a glass bottle on his doorstep, he started it.
That would be quite hurtful to your neighbor if they tripped on it. If you are upset with them, confront them politely and not with dangerous pranks.
He shouldn't have woken me up at 3:00 am just to tell me this.
Broken glass can can serious harm to anyone walking on it. If your neighbor is annoying you, let them know your reasons and see if you two can come to an understanding.
