'keeping it for best'
Yep, me too. I grew up in the '70's. It was definitely a case of looking after your things. Not necessarily keeping them for 'best' , but certainly having 'smart/tidy' clothes/shoes for 'going out' & that was visiting grandparents/going shopping, not just some major event.
My parents had a 'best' dinner service, but it was used frequently with people coming around for dinner Same with glasses 'good ones' used but not every day.
I'm much the same. I don't use 'tat' day to day, I use nice things & I'm naturally careful with them anyway, but I also enjoy having some things that are 'special' not 'everyday'. But I definitely use them.
My problem with creams & lotions, is that I don't really use them, so they tend to build up & I can't just throw them away. I feel terrible giving gifts away to charity shops, but I try to not feel too guilty & try to focus on the fact that at least they'll be appreciated by someone, if not me.
But I have FAR too many opened bottles of lotions & creams (and goid friends are worse than me, so I can't off load to them!)
