We bought our house a year back and have never spoken or seen our neighbours on one side. Today we had some guests over and we were chatting on our patio furniture from about 7-9pm as it was too hot indoors. We have a detached house but neighbour was in her garden too and suddenly around 9pm started yelling about us being so loud and always shouting, never talking and being very annoying. When she said it we immediately said we apologise if you’re getting disturbed we’ll move inside in few minutes. She went on shouting and sprayed water with hose on our guests and my elderly parents. We were shocked and embarrassed in front of our guests. We never have guests outdoors except few summer weekends and are usually quite during the day, may have a noisy few hours daily before the 5year olds bedtime. We don’t drink or party in the garden/barbecue or play loud music ever. I’m so scarred by this crazy rude behaviour that I feel like moving far away from the lady. Am I being unreasonable in thinking I need to complain about her to local services?
