Pro Life Tip: Use the "Hide" function so that photos are off your main camera roll. No sudden discoveries if someone decides to swipe around. Yes, someone snooping can still hop over to your albums and find the "Hidden" album, but that takes a few more steps if they're aware of it.
In addition to the typical nosiness and insecurities (e.g. photos with friends or co-workers, travel, restaurants and home cooked dishes), you'd be surprised what snooping exes and family members would get mad at... other people's baby photos, art or other interests that they didn't like the style of, photos from solo activities because we're individuals and we don't have to do everything together... "Do you have something to tell me?" "This is horrible. Why do you like this shitty [thing]?" "Why didn't you invite me?" "I see you don't care about me / only care about yourself" "Why do you want to buy that? I'll buy you something better" then buys something I don't want.
Pro Life Tip #2: Don't put up with people who snoop and want to control what you can or can't do or like, unless they're actually helping you or protecting you from danger (e.g. medical, fire, police). Yes, that includes family. Set good boundaries. Life's too short for this kind of bullshit.
Pro Life Tip #3: I recommend showing but not sharing anything too "valuable." Definitely share what you want to and can safely share, but the moment you send it to someone, it's in someone else's hands and they can do whatever they want with it. And instead of sharing photos, there are many things that are better shared in person... 😉
