One of the things that characterize people who are from Madrid is speed. If you are living in Madrid or going to Spanish school in Madrid, you have to start running.

You're not from Madrid if you haven't spent a Sunday in La Latina. As soon as it's a little sunny, the real people of Madrid throw themselves into the terraces of the bars.

Nor are you from Madrid if you haven't visited each of the most famous markets: design market, engine market... These places are absolutely essential for any good Madrilenian.

You're not from Madrid if you haven't had a good “cocido madrileño”. If you are studying Spanish in Madrid, it is a must to eat a good "cocido".

Neither are you from Madrid if you don't know perfectly the "Búhos" (night buses). Madrid is huge and has many festive areas. Testing each and every one is practically essential.

They'll save you from more than one situation.
If what you want to prove is that coming to learn Spanish in Madrid has been worth it, you will have to drink the grapes at Puerta del Sol on the 30th.

If you've been in your language school long enough, you've probably already noticed all these situations. If not, you know all you have to do to be a real Madrid native.
