Definitely a change in temperature. Was round at my folks and they had their heating on and my mum also had a halogen heater on. It was absolutely roasting. I wonder what they will do when it gets cold. Today I'm working from half 1 to 10 🙁
Aye I'm like your mum always cold my feet are freezing just about every night as they are now got on thick socks. I put the heating on and Sue moans at me as she get toasted .
You must do a lot of worrying about your parents as I did my dad.
