Sounds too random to be meaningful, (for me)
But strangers on the internet are not telepathic and don't have access to your subconscious
Having said that, in some countries, China and Japan, you are not supposed to, smile in photos. It looks not serious
Likewise I have always wondered , what is the point of smiling in photos?
There are five emotions and happy is just one of them
It should not be necessary to put on a facade
