Perder la costumbre

[ROBINDESBOIS]

In English?

Ejemplo:

Para no perder la costumbre, voy a ir a comer a casa de mi madre hoy también. ( significa que voy todos los días, aunque viva en mi casa)

[Rusty]

As always, I'm also going to eat at my mom's house today.
As usual, I'm also going to eat at my mom's house today.

[poli]

....also a completely acceptable direct translation is:
So as not to break the tradition, I am going to eat at my mom's house today also.
