Pre-Valentine's flowers

I usually take my mum a bunch of flowers. Today was no exception, and because of Valentine's there were plenty to choose from, as long as the colour red was what you were after. I wasn't but had no option. Although she can't see them, she loves having them in the house, and she has the knack of making them last for weeks. Something to do with changing the water and keeping the vases in a cold room overnight, or so she says. Me I think they feel the love!
