Oxalis leaf

I had been admiring this leaf on the Oxalis plant at work for a few days, watching it slowly change colour from green to red and brown....then I was ill and off work for two days and now it is looking a bit brown and dried up! 
Never mind, I still think the colours are great!
I see this is my one thousand seven hundred and second entry, I somehow missed 1700! not long now to my 5th anniversary!
