At the swimming pool. Woman and friend plus ds of about 4 and dd of about 2. Children having a lovely time. Every once in a while one or other of the children would turn a delicate shade of green and the mother or friend would hoik them over to the side of the pool where they would be copiously sick in the bushes. Child would sit quietly for a few minutes, before leaping back into the pool and continuing having lots of fun.
Now surely, either
(a) the children have a tummy bug, in which case take them home before my children and everyone elses get it, thanks.
or (b) the children have some sort of non-contageous, long standing allergy or something, in which case be more organised than to let them vomit in the bushes by the pool where everyone is playing.
Can I judge in horror? Or is there a perfectly uderstandable and reasonable explanation for this?
