OK story is DD is 4 and goes to Jazz class which she loves. There is another girl there who is always really very poorly. I mean temperatures, sickness bugs, viral infections poor little thing. Every week she is in class looking dreadful and her Mum tells me how ill she is and how she has just had a spoon full of calpol, this week it was "just been sick" 
I am completely perplexed that her Mum still brings her in. The dance teacher is lovely and as the girl manages to scrape through the class doesn't really know the extent of the illness. D and this girl are good pals and always pair up, hold hands. DD has caught the last few bugs this girl has had and I am really fed up with it now. I was thinking of having a word with the teacher but don't know how to approach it or if she will think I am being odd to ask her not to pair them together.
