So this is a Facebook thing, I'll admit it.
My profile picture is of me. It's never not been of me, albeit I have a cartoon version and other such fluff.
DP's is of him + me. Not for me, but I do use a photo of both of us for my cover photo.
What I can't get my head around, is why people plonk up photos of their mates where they aren't in the foreground. Or plonk up photos of their kids where they aren't in it at all. (I get the latter a bit more than the former to be fair, but I think it's a bit sad to be posting it as your 'identity').
So AIBU? I suspect I am, because I view my photo as my online 'identity' so wouldn't want it usurped by DP / theoretical kids / random mates, but others may not think that way.
I do get the whole 'look I've had a baby' thing of changing it to the newborn, I really do (even if I think it's a bit naff) but not your 8 and 10 year olds - they are not you...
