Can't you just keep a photo album of those people or anything? Maybe one day, you'll stop liking a family member. What'll you do then?
I've never lost a photo in my life; especially not now that they've become digitalised, which makes it far more easy to make infinite copies of it, and thus never lose it.They're still your family. Flesh n Blood n Bone. Even if you fall out, that relationship will still be there. And anyways, It will be personal to me because I have a strong connection with my family.
Photos can be taken all the time. And you can lose photos quite easily. Tattoos are a life time commitment and are much more personal in my opinion. And unless you get your body part hacked off its a lil harder to lose a tat than a dear photo! xD
I don't mind tattoos. Piercings I don't have a problem with either, unless someone pierced their personal body parts. Then that's just...disgusting.
