Changing bedsheets periodically

I'm one of the laziest people around. Honest. And stuff like changing sheets doesn't come easily to me. But my mum used to force me to change my bedsheets periodically - and she'd help me do it. The fondest memory I have of this repetitive exercise is the new sheet! Seriously. We always used cotton sheets in our house, and having a fresh, crisp cotton sheet on your bed makes your bed feel very very cosy and inviting. I soon got the hang of this - and actually looked forward to these sheet-changing times. Later on, when Mum tried pushing some synthetic sheets on me - I staunchly refused. Only cotton sheets for me. For this lifelong love of fresh, clean cotton sheets and the cosy under-the-covers feeling that they bring, thank you Mum.
