Since I moved out of London, I’ve started to see the city in a completely different way. I still go back once or twice a week, so I stay connected without getting overwhelmed by city life. It’s like I instantly put on a pair of magical rose-tinted glasses the moment my train pulls into Euston Station, and they stay on until I leave.

One of the things I enjoy now is taking the tube, which I used to despise. I would avoid those crowded, hot carriages at any cost. But now, I actually enjoy it.

I love the thrill of gliding down the escalators into the underground. I enjoy people-watching or taking a moment to read a book during the journey. I appreciate how quickly I can zip across the city and pop up in a completely new area.

Here are ten things I’ve noticed about the London Underground, along with some survival tips for first-timers.

1. Everyone feels like they’re in a shampoo commercial
When the train rushes through the tunnels, it sends a warm gust of air ahead of it. Sometimes it’s dirty, but other times it feels nice and cools you down. If you watch the people with long hair, you’ll see their hair blowing back like they’re in a glamorous shampoo ad.

2. Everyone feels like a superhero
There’s that split-second when the doors are about to close and you have just enough time to leap through. In that moment, everyone feels like a superhero. You leap through, the doors close behind you, and you can’t help but feel a bit smug for saving yourself a couple of minutes.

3. Everyone gets wary of damp seats.
If you find your seat is damp, never touch it or sniff your hand. Do you really want to know what it is? Just stand up slowly and walk away.

4. Everyone dislikes people with suitcases
Or backpacks, or pushchairs, or anything large. We all have to bring these things on the tube sometimes, but it doesn’t stop us from getting annoyed at others for doing it.

5. Everyone hates it when you stand on the left
On escalators, you’re supposed to stand on the right. There’s a sign that says it clearly. If you stand on the left, be ready to walk. And honestly, if you’re under 70 and have two legs, you should walk.

6. Everyone gets frustrated with tourists who don’t know how to use Oyster Cards
This sounds harsh, and I apologize to all tourists who struggle with Oyster Cards. I probably struggled my first time, too. But when you encounter tourists daily who can’t figure out how to tap in and out, it gets annoying. Just hold your Oyster card to the yellow disk, and the doors will open. It’s that simple.

7. Tall people will never understand
Tall people can’t understand how bad rush hour is for short people. It might be hotter up there, but down here it stinks, especially when someone’s armpit is right in your face.

8. You need something to read or do
You need a newspaper, book, phone, or tablet. It’s a must. Otherwise, we’d all have to look at each other, and that might lead to talking, which would be awkward.

9. You’re surprisingly safe
As long as you’re sensible and stay alert, the tube is pretty safe, especially when it’s busy. There are so many people around that it’s difficult for pickpockets and thieves to get away with anything. Still, keep your belongings secure and avoid keeping valuables in your pockets.

10. Everyone complains, but it’s really quite amazing
Despite all the complaints, the London Underground is one of the best city transport systems in the world.
