Mothers' Day

Stuart is visiting this weekend so as the weather was really rather good this morning, we joined the hordes at Charlecote Park treating mum to tea and cakes.  A walk around the deer park followed and they asked me to photograph them together ... I did ask them to stand in the shade under a few large trees to avoid the bright sunlight and harsh shadows,  should have had them stand further in ... I'm not terribly good at this family group malarky!

Is it Mother's day because each of us just has the one,  or Mothers' day as there is the one day but many mothers?
