Good to here a photo touched you in such a way, I come across pictures that do the same thing at times. When I here a reaction like this it's very rewarding... Thankyou for sharing.
This... 
photo
will trigger those sorts of memories in my wife's family in years to
come as Ruth passed away last week. Whenever anyone visited Jack and
Ruth you'd be treated to tea and biscuits while they sat in 'their'
chairs. I snapped this pic whilst waiting to take a 4 generations
photo of Grandma, Nana, my wife and our boy. When I posted this pic
sometime ago, someone said they looked like they were watching TV,
but they are actually talking to my wife and the plate is empty cause
the fruit cake hadn't been put out yet or the tea had yet to be
poured. The biscuits had been placed on the plate ready for
consumption :)
For the technically minded, the film was Konica IR750 (no filter), 28mm lens and exposure of 1/2 sec @ f2.8 (camera was on a tripod, I just waited for a Grandma to stop speaking before tripping the shutter).
I'm very glad it came out ok.
