are missing out
Estás perdiendo demasiado tiempo.
You're wasting too much time.
You're losing blood.
No sabes lo que te estás perdiendo.
You don't know what you're missing.
Estás perdiendo contacto con la realidad.
You're losing touch with reality.
— La vida de los otros (2006)

¿Estás estudiando para el examen o estás perdiendo el tiempo?
Are you studying for the exam or are you wasting your time?
You're losing me.
