I’ve just spent the weekend in a rather chilly Birmingham. We had a lovely time however every time we went out in the car in the morning we had to clear the ice from the car windows. If we didn’t do that then mum wouldn’t have been able to see clearly to go on the journey. Even the smaller parts of the windows were necessary (which I may not have necessarily realised as a non-driver).
All sorts of things affect our vision and ability to see clearly – practically and metaphorically- it’s important to recognise what those things are do what we can to clear the way and make the journey.
