You're like a slow walk and a cup of tea
Has anyone else ever encountered the expression: "You're like a slow walk and a cup of tea"? I remember my grandmother using it often when I was a child in the North East of England. I think its meaning is pretty obvious, but I'm curious to know if it was, or is, generally used (at least in some parts of England) or just something she made up herself.
My background is in the south-west of Ireland and now the south-east of England and I have never heard it. My partner is from north-east England and I will ask her if she has come across it.
