In at least 2 to 3 sentences discuss why group (or more than 1 child per sink at a time) hand washing is not a sanitary practice.

because it is making there not as clean because other kids nasty soup is getting on your hands.

Explanation:

If multiple children are at the sink, the caregiver won't be able to make sure each child had is properly washed. This could also lead to children playing in the water and not washing their hands. Also, this is unsanitary because the other kids' dirty water/germs could get on the other kid, and said kid wouldn't have properly cleaned hands. 

i can't answer your question in very sad situation.

but if your situation is very bad, then you can find happiness by thinking about your past that has full of happiness.

or you should do meditation for some time to get rid off from that bad situation.
