If you're not planning on overdoing it for your Mom today, overdo it for all the rest of us who would give anything to overdo it for ours
Hey Mummy, remember that Mother's Day I carried a tray of food into your bedroom loudly singing Dean Martin, and you threw a book at me in horror? Or the time you flipped an entire plate of mie goreng onto your head on our last holiday, only to have you say in a sheepish little voice "oh... shit!" Or the time we just sat at that Starbucks in Paragon giggling for hours on end while people around us tried to figure out why? Good times! :)
I love you Mummy. Being silly just isn't the same without you.
