Tell them you’re Roman Catholic, they then use the opposite side of the street to pass your house. Come to think of it, I must scratch out my cross, they invaded my area last weekend.
And the next bugger who chooses to attract my attention by banging on my gate with a key is either getting a pot of paint and a brush, or will have a no 11boot stuck in their arse.
Answering the door practically unclothed also keeps them away. Most of them at least.
