Inspired by this BoredPanda thread inspired by TV, this is the place to tell stories about sibling quirks.
I am just thankful my brother isn’t a Doper.
Yes, that would be bad. (My bros, not yours).
My brother was being harassed by some guys in school, so he bought them off with hard cider he made. I watched him gather a burlap sack full of granny smiths from our tree and extract the juice using his baseball bat.
Did it work?
He could have saved a few steps by applying the bat directly to the bullies.
That might work better after giving them the hooch.
I can’t even…
I have a younger sister who never washed her hands after using the restroom, nor does she wash them before eating. She only washes them if they “look” dirty. Somehow she’s the healthiest person I’ve ever seen, I’ve legitimately never knew of her getting a cold or flu ever.
As far as I know, it did, though, the next year, when he started HS, he decided to enroll in the new experimental school across town. For some reason.
Also, we both used to walk around on the ceiling. That may have been his idea.
Well, my brother ate ants. He’d squish them with his thumb and lick them off, to the horror/admiration of the other neighborhood kids.
Once he added water to our tube of toothpaste, to save time wetting his brush…and yet another time I found a bar of soap in our bathroom with a perfect bite taken out of it. Don’t know what he was thinking.
Mine didn’t…
because I was the weird sibling.
For me, this.
Except for the past tense.
I only opened this thread to see if I could recognize myself in one of the responses and then I’d know if my sister was a secret doper.
OT
In one apartment, I rigged up a shower in the clawfoot tub. The soap sat on the toilet tank. One time, I started up a shower, reached for the soap, and it was not there. After some searching, I found the soap under the tub. It had tiny teeth marks all around the edges.
We had rats.
(And yes, I used the soap.)
My sister decided one day to move to Nebraska. And then she DID! 
My brother once placed a large hunk of chewed gum on the bedpost overnight, to see if it lost any flavour.
We tried that too. It took the paint off the bedpost, so we never learned the answer.
Do tell.
