I know I probably am BU but I just need to vent. I'm tired.
DS 15 months is a light sleeper. I came home from work at half 9, DS woke at 9:45 and is still awake now. There is a dog constantly barking. It's incessant, loud and it's keeping DS awake. AIBU to feel extremely annoyed? 
I won't be saying anything to the neighbour, but I do wonder why they can't do something about the noise.
