Good Morning Sprinkles. xx

Saturdays riddle answer was - A King.
*******************************
Yesterdays again in case you missed it.

I am your friend who rings the bell DING-DING,
Sometimes I even push you on the swing.
I am probably where a person goes,
Usually I go up your nose.
Without me friend you'll probably die,
Now I ask you what am I?
****************************
Todays is:-

We hurt without moving. We poison without touching. We bear the truth and the lies. We are not to be judged by our size. What are we?

All answers on my back wall please. xx
