What would it be like if we had to use punctuation when speaking>
I say comma old girl comma.do you fancy a night out question mark
Yes comma she replied cheerfully full stop.Where shall we go question mark
Not very appealing, is it?
In oral communication, we use the tone of our voice, emphasis on certain words, our facial expressions etc to make what we say understandable.There is a big variation in how much affect our feeling we put into our voices too
How are you,dear? can sound very caring or quite brusque.This is something we need to think about.We may not be getting across to the other that we are really interested to know how they are.
And as a listener [ which is a skill many of us lack] are we hearing what the other person is telling us or are we on automatic?~
How my heart sings 
Also, a lot of people comma communicate through text message comma and often interpret messages wrong full stop Tone is difficult in text messages but punctuation can assist in this full stop I like this topic full stop
Thank you so much Eilidh.It is a topic which causes controversy
