We took kids out to the Aquarium yesterday (we and 3.000.000 other parents !!!!) anyway when we got to the ray's tank, where you can touch them... my kids and other kids were gently stroking the rays (encouraged by the staff).
A mother said to her 6yo (?) child to get his hands off the water.... he didn't, she smacked his arm... (his dad said it's OK just roll your sleeves up).
Her point was that he couldn't wash his hands afterwards and then when he did dis-obey her (she continued telling him off) she said "don't put your hands in your mouth...."
Now me think... OTT mother.... can your child not go to the seaside and swim in sea.... nearly said it 
What do you think ?
P.S. Rays were from the British seas.
