DH has told me I don't have any hobbies because I don't do anything with other people (in person or online). I thought I had lots of hobbies: gardening-i have an allotment, bird/nature watching and photography (I don't share the photos online or anything), reading, swimming, art and painting. But is he right? Do people think of these as just interests, that only properly develop into hobbies once you start joining groups, competing/cooperating, sharing knowledge etc.? Are hobbies inherently social? If they can be carried out alone do hobbies still need an element of comparison to others, such as knowing how good your score/level/knowledge is compared to others or is it still a hobby if you just enjoy it for what it is, on your own?
YABU: hobbies are social
YANBU: hobbies can be solitary
