Who here has a memory you shared with an older or younger sibling when you were kids?

I remember when I was a kid, I was like the devil child. Running away, hiding, loud, throwing up. My older sister was like a little angel, she was quiet, polite, had manners, etc.

When we were both around 12-13 we basically did a switch. I started acting responsibly, logically and with impeccable manners. My sister went through her rebellious phase with my parents and a lot of stuff happened.

Now things are pretty even and level between my family.

But I remember funny times when I was a kid with my sister.
My mum told me that apparently my sister used to dress me up in dresses and other costumes when I was a toddler.
I remember when my sister took up all the space in the bathroom which meant I had to brush my teeth in a 0.5m x 1m washroom.
I remember when my sister jumped on my head and cracked my skull.
Or when I accidentally kicked a soccer ball in her face and I was begging her not to tell mum and dad (I was already on thin ice for something else I did).

The last and best one was our deaf dog. He had never barked in the 7 years we had him. But one night when I took him out to watch my sister practice netball scoring, he would bark every time she shot for goal. It was amazing. He has never barked since.

So, who else has some fun sibling stories?
Stuff that at the time was scary or stressful but when you look back on it, it was fun and exciting.
