Last weekend I went to the local Orchid Show  - so many beautiful orchids - they brought back memories of my grandfather's exotic and glorious orchids that grew in a lovely old glasshouse at the bottom of his garden. 

As a young child, walking in there was like stepping into another world -  the moist sandstone rocks underfoot covered in spongy, soft green moss, fragile maidenhair ferns self seeding in little nooks and crannies surrounding the feet of the pots from which magnificent fronds of exotic orchids bloomed.  Oh the smell - that earthy, moist, almost musty scent of decomposing vegetation and potting mix - I loved it!   And then there would be the moments when the sun would shine through the glass ceiling and strike the fragile filaments of a spider's web swinging so softly amongst the greenery.

I wonder if you have had a similar memory  - and how a scent of something can so strongly bring back the moment.
