SEGUIR + GERUNDIO — not what's happening, but what hasn't stopped
The office is packed up. He sits down anyway. Seguir plus gerundio is not what's happening — it's what hasn't stopped. Estoy esperando (right now) versus sigo esperando (it's been a while and I haven't left). Watch the e turn into an i: sigo, sigues, sigue, seguimos. Twelve episodes. You're still here.
