I use to have a hot water bottle when I was a kid. This was when the bed was cold. It felt really good having the water bottles near my feet and legs when I was in the duvet cover. Back then, we never use to have radiators upstairs so it use to get pretty cold.
It's nice to be surrounded by things that carry good memories. The brain is generally better at remembering negative things, so it is good to give yourself some support in remembering the better things. I always buy a few things when I am on holiday for just this reason, if only a fridge magnet.
Indeed Kerome. I have bought straws, a space hopper and today I bought party bags as I'm throwing my older sister a birthday party. I think as a child I was thrilled when I took a party bag home with cake inside.
