So I said to t'old man on a wet April afternoon
"while i'm stuck indoors, i'll wade through all those old programmes and souvenirs that i've got stashed in boxes"
The idea being to free some cupboard space and incorporate a bit of spring cleaning.
So I got them all out, scattered the various 'piles' all around and a spent a lovely couple of hours wallowing in nostagia 
"Where's all the waste for the rubbish bin then?" enquired t'old man much later.
"Errr...here it is" I muttered as I handed him a couple of old travel brochures and some scrap bits of paper.
"Is that all ?"..he asked in bemusement
"Well Yes".....after all how can I possibly throw away the special viewers that we were provided with when we went to witness the eclipse in Strasbourg in 1999..or the Arena de Verona tickets to see Carmen in 2003..or the plastic spoon sets we brought home from EuroDisney when I took a 9 year old Bella there in its first year of opening in 1992...or all the programmes from our broadway theatre visits and the folk festivals..........................

So understand. Throwing stuff away makes me panic. I hate to do it.
It's supposed to be good for you, decluttering but it could be just hype.
