I do believe Kinder eggs are significantly smaller these days than they used to be. Or maybe I'm just taller than I was when I was seven.
In any case, they're now expensive enough that you're basically just buying a toy for more than it's worth, without knowing what it is, and you can't ever return it to the store because you've eaten the packaging.
Diane, I still don't know if you were making a joke based on it being a kindergarten for children under 6, or if THEY were making that joke and it actually is a gardening course for children under 6. Personally I wouldn't trust a 5 year old with a trowel - under sixes are remorselessly violent.
In any case, I have no interest in being kinder to flowers, as they're certainly not very kind to me during the pollen season. Those green petally gits.
