It is Christmas Eve in the busiest aisle in the busiest supermarket in the world. MrsM is trying to avoid being crushed by shopping trolleys pushed by women who would rather be power-walking. MrsM hears her phone go and tries to get it out of her pocket without injuring the small child who is being used to dart between trolleys to reach the biscuits on the bottom shelf. It is MrM phoning from his annual shopping trip "I am at the shops!" MrsM feigns surprise."I can't remember what sort of cream you want" MrsM mutters into the phone "I said I wanted night cream" and hopes no-one can hear her. MrM says "But there are two sorts of night cream - the grey one and the black one" MrsM immediately recognises her plan to introduce new concepts to the gift purchasing routine has the potential to go tragically wrong and hastily replies "Just plain night cream" "One is wrinkle cream - do you want that?" MrsM starts to panic and whispers "I want ANTI-wrinkle cream" MrM says "I can't hear you - can you speak up" Which is why MrsM found herself shouting into the phone on Christmas Eve in the middle of the busiest aisle in the busiest supermarket in the world "I want ANTI-WRINKLE CREAM".
