4.30pm last night.
Durham Lumiere foot patrols.
Unkempt drunk man shouting & swearing at passers by.
They looked on in horror & disgust.
I looked on with compassion
I saw beyond the vulgarity.
I saw a very vulnerable, broken man.
A man who needed my help.#BlueLightDay pic.twitter.com/vREaxUHzpI

Today is #BlueLightDay! Working as part of a wider team is vital in what we do. On an almost daily basis, we work shoulder-to-shoulder with police, fire service, ambulance, and others. They may not all require donations but all deserve our appreciation and respect. 🚑🚒🚓🚁 pic.twitter.com/9xC9ouLOsS
