Painting the brick is a repetitive action and it also symbolised in our life, we by be doing similar things for most of the time, for example, us student go to school from Monday to Friday, we have our weekend holiday on Saturday and Sunday and after that cycle repeats, we may get bored of it eventually and we may want to give up, but the ladder symbolised that after all the handworks and all the steps that we climbed, we may reach to the top and see the beauty beside the wall, and realised all the hard work that we did finally paid off.
