Years ago I probably would have kept my interest in railways and railway modelling to myself, but now, at the ripe old age of 47. I don't care who knows or what they think. When I was at Sheffield Poly i'm sure the other metal heads I was hanging out with in the Wapentake pub and at gigs were totally unaware that I spent a lot of free evenings walking from my digs over to Beighton yard to catch freight moving through and to take crap photos of said freight, or that my favourite shop to visit was Beatties.
Working in "Nerd Central" (Maplin) for the last couple of years has probably made me more aware that it's ok to talk freely about my rediscovered hobby. It actually has been helpful in making sales of small components, solder, tools etc and on more than one occasion i've ended up spending time with customers showing them photos of my layout on my phone and looking at photos of their model railways,cars, boats, planes, spaceships, dollhouses.......the list goes on. It's even helped me sell Google Home speakers when I tell people I have one in my shed which I use for listening to Planet Rock radio while i'm working away.
I was quite surprised to that see one of my neighbours had liked a few of the photos I'd put onto the British Railway Modelling Facebook page.
Once people realise that you are talking about something more involved than Thomas on a circle of track on the living room carpet, they tend to be more interested than scornful.
