this is how the conversation went ...
me "kids, you know we are heading out for an amazing/exciting/warm holiday at easter?'
kids 'yes, we are sooooo excited about it"
me "well, as part of going on holiday you need to have a few jags (yes, that's what we call them in Scotland)"
kids "nooooooooooooooo" (followed by *fake* tears and much arm flailing)
me "if there is any sweet in the whole wide world that you would love I will buy it for you so you can have it after the injection"
kids "oh, alright then ... fruit pastels please"
