1. Your face is pushed into the birthday cake.
My favourite Mexican birthday tradition is “la mordida,” when the birthday girl or boy’s face is shoved into the cake for them to take the first bite, whilst everyone around them shouts “Mordida! Mordida! Mordida!” Note that Mexican cakes are pretty creamy.
2. Mariachis serenade you as the sun comes up.
I’ve lost count of the times I’ve been woken up by one of my neighbors being serenaded on their birthday at 6am. The sounds of mariachis singing “Las Mañanitas” (“Little Mornings”) drifts through the window. While it’s beautiful, I always think if it were my birthday I’d prefer they arrived a little later.
