Dearest Colgate Toothbrush,

I always wait for that time of the Day when you come and hold me close, throw yourself upon me. When you caress all over my body, it brighten me up. Indeed you are only who can reach deep inside and make me happy. It makes me feel so nice that someone cares for me so much.
Missing you so much honey!
Never leave me I am yours forever

Lots of love
Ms Teeth

For better understanding I am explaning each sentence in details:

I always wait for that time of the Day when you come and hold me close, throw yourself upon me.(the morning or night at the time we brush our teeth )
When you caress all over my body, it brighten me up. (brushing the teeth from all sides)
Indeed you are only who can reach deep inside and make me happy. (reaching till the root of the teeth)

Kinldy check my letter for grammar errors if any. And if you can add up anything to make it more interesting, Its my creative writing assignment.

Thanks in advance!
