Taking photos...my dad is the shutterbug of the family.
He likes to be behind the camera, and so that means there are hardly any family photos of him and all of us. He takes them for memories, but I generally dont like having my photo taken. That wont mean i will refuse to do it but i think many people dont always like to have it taken cos they might not want to smile, feel like their clothes are shabby, or are not photogenic. Also photo sessions can sometimes take ages so if you one of those ppl who are always asking for people to pose for you it can be tiring.
Oh and people taking pics of you eating...?! Im terrible at taking photos and im not one of those people who do selfies or post to FB. But it is important to have those memories too although I prefer writing to a photo.
My dad loves photogrpahy so much he will go trainspotting hoping to catch a train so he can take a photo of it. I dont get it but thats what he likes to do. It makes him happy! The trains are usually not bothered if he takes a photo of them. All they have to do is turn up on time.
