If there is an extremely popular student, for their birthday there will be a party. Tearjerker parties, since classes are always very close-knit, and everyone becomes friends. In this case, all your friends, regardless of what division they're in, go to your party to say goodbye. And some teachers too. Especially Colombian schools.
Colombian people are extremely nice people.
If you're new, you'll be the school celebrity for weeks . Everyone will want to get to know you and become your friend. Sometimes the new-ness will never wear off. People asked me to no end about myself, and life in USA when I returned to Colombia. It never stopped, either.
