Strangest Traditions and Habits People Have

What are the strangest habits you find about your fellow human beings, or even yourself? Even if it's really daft, feel free to add.
The Top Ten
1 Getting Out of Bed On the Same Side Every Morning

My bed is not against a wall. I ALWAYS get out of it on the left-hand side. I tried the other side once - completely ruined my day.

My bed is enclosed between two walls, so noise isn't really a problem for me. In fact, I'm in bed right now, and speaking of which, SOMEBODY HELP ME FOR GOODNESS' SAKE! I'VE BEEN HERE FOR TWO YEARS AND I HAVE TO GO TO THE BATHROOM REALLY BAD! I'VE BEEN EATING MY TOENAIL CLIPPINGS AND DRINKING MY SPIT! And oh gosh, I'm out of character-er, uh, I mean, my bed is comfy.

Dad: "Who are you talking to, son?"
Me: "Oh, nobody, Dad. But wait, I'm not talking..."
Dad: "Oh, what, you're not? Geeze, uh, about that, you were typing real loud and, uh, the bacon is ready, and I just gotta go!"

*Sound of getting into car and driving away*

I have to because it's against the wall.

2 Sitting On the Same Side On Public Transport

Again, I try to sit on the left side of the bus / train. It upsets me if there are no seats on my favourite side.

Yeah I find this. I always have to sit on the right-hand side when driving.

I love sitting in the window seat!

3 Singing to Advert Jingles or TV Shows

I've tried to stop imitating the EastEnders drumbeat or advert jingles but I can't. There's no cure.

I sing the Meow Mix Tender Centers commercial sometimes. Yes even the non singing part.

My parents do this

4 Having a Favourite Chair at Home

What is this "chair" you speak of? Might it be related to... THE COUCH!?!? *insert beautiful heavenly chorus here*. But yeah, who uses chairs anymore when you can lounge back in the cushions of your couch and get stuck. I have been stuck and am suffocating from leaning back in my comfy couch and having the cushions enclose around you

I don't have a favorite chair, but I do sit in the same chairs all the time because my mom and sister doesn't allow me to sit in their chairs

Haha I'm sitting in it!

I'm sitting in it!

5 Always Adding Mustard Before Tomato Sauce On a Hotdog
6 Pull Random Faces In Concentration

My friend always pokes her tongue out the side of her mouth or wiggles her eyebrows. Cute but a strange habit.

7 Adding Milk Before Tea

This is not the 'proper' way to make tea. The rule is: tea first, then milk but I, and many others don't follow this rule.

I always add the milk first so I don't have to let it diffuse for as long. It's an advantage.

8 Knock Three Times On the Door
9 Laugh When Embarrassed

Good for you, Cookie. Join if you will, any time you like.

I actually find this strange on how it works so well!

10 Say "Umm..." Before We Answer a Question

Don't think this is strange at all. We all do it in some times.

Even if the question is, "What is your name? " someone will always reply with, "Er,..."

It's probably natural
