Theres no point in crying over spilt Milk!

They say a problem shared is a problem halved, so does this give me permission to stand up in Starbucks and shout my problem at the mothers meeting who have clearly disregarded their children letting them run wild screaming?, All I wanted was a quiet stress free £1 coffee to get some work done! This is my problem, on top of the normal banging, steaming and shouting from the baristas the crescendo from the children make it unbearable. So please tell me if I do stand up and scream my problem at all 5 mothers, will this half my problem as I've been so wisely informed from our TV doctors?
