Saturday morning in the art gallery cafe

I know this woman slightly, having met her on the bus many times. (There's a sort of cameraderie among regular public transport passengers that you won't be aware of  unless you are one of them.) 
I know she's recently turned 90. She knits all the time and today was wearing a rather fetching crochet hat with a matching jacket, all hand-made. She was planning to catch the next bus into our county town to read the magazines in the library there but first she was going to have a ham salad with thrice-cooked chips, a speciality of this cafe. Although by next month, said the proprietor,  last season's potatoes will be too sweet.
