The Bible says, be kind to your neighbour. I got a great lesson in that when I noticed the house next door being renovated. I needed to do some re shingling to my own home so I sparked up a conversation with one of the workers. He was busy and left a business card. After asking my neighbor how the work went, as I was interested in a referral. He told me it was smooth and painless. I decided to give them a shot and it paid off.
