I thought a one-stop shop guide might be useful! I'll start.
If you want to annoy your neighbours with maximum efficacy....
Prance in your garden in a bikini (note: simply wearing it will not do)
Be naked in your garden

Go on holiday thus meaning you cannot feed their cat when they are on holiday
Leave your tiny tiny thongs on a washing line
"Helpfully" take in their: laundry, bins, parcels
What have I missed?
