sketching in the sea mist

My daughter, currently studying illustration, is sketching every day...and so I intend to join her, at least some of the times!
We had intended to go to Brighton beach, as the day was hot and sunny. But over the downs we were greeted with a grey damp rolling sea mist...so we ended up at the Marina, and instead of the intended ice creams, we had coffee at Cafe Rouge.
My daughter sketched the boats, and I looked up at the cafe. I resisted the pen today, but it was hard!!
