Cold or fresh?

Sunshine and warmth, so we stayed in Helsingborg and went down to the sea. Water more salt than ever. Freezing, so no swimming. A young man overheard me complaining about cold and he stated that it was not, it was fresh. 18 degrees cannot be cold!
Later on we drove north. My sister C to the summer cottage and I to visit my youngest daughter. How I have longed to see her!!
