I grew up as an only child, and even though I have a sister now, sibling dynamics are largely a very interesting mystery to me.
One of the most mysterious is the sibling relationships with significant age gaps.
I don't mean 5 or even 10 years — I mean a gap where it's not uncommon for people to assume your older sibling is actually your parent.
So, if you have much older siblings, tell me in the comments about the weird experiences you've had for a chance to be featured in a BuzzFeed Community post.
