I blame the flowers my mum bought yesterday.
I don't actually like cut flowers - they are destined to die within a week, because they have been orphaned from their plant. I quite like plants. But being allergic to bloody everything, I try to limit sources of allergens within my own house. For instance, I mostly only buy food I can eat, because it's much easier to check the label in the shop than when at home with low blood sugar. Anything that Richard wants that I can't eat gets put in one particular cupboard that I know not to go foraging in when half-asleep. Plants are an enormous source of allergens - between pollen and scent and sap allergies, I wouldn't bring a plant into the house unless I knew I was ok with it. But if you're female, people will insist on giving you cut flowers. Why?!
I would take these up to the hospital and donate them for random cheering-up purposes, but that would mean having to breathe in their noxious itchy vapours for a whole 10 minutes of hell, and probably donations of flowers from strangers are banned for security or MRSA reasons nowadays. Bah.
