Dull day

Weather dull but dry.  Met a friend for coffee this morning and then walked along the seafront.  Came home had dinner and S came round so we went to Priory Park for a walk.  It was lovely in the walled garden of the priory and later we stopped and listened to a group playing at the bandstand before coming home.  The sea was so still, lots of boats, yachts and people in and on the water, together with people relaxing at their beach huts.  Very clear and I could see across the river to Kent.
If anyone knows what the yellow flower is called I'd like to know, it was very tall.
Sorry so behind again with comments
