So I've been invited to the beach with some friends and family which is an hour away (herne bay) from where I live on bank holiday Monday when it's meant to be really hot ..so I struggle a lot with the heat and what to know whether it's wise to put myself through the hour drive in a hot car? Then sitting on a beach all day even though I'll have one of those sun tent things? It's still going to be hot then also it's a stone beach and I don't have any chairs so hardly going to be comfortable 🤦🏻♀️ How do I say no but actually have a good reason?
