Relax. Concentrate. Dispel every other thought. Let the world around you fade.
Best to close the door; the TV is always on in the next room. Tell the others right away, “No, I don’t want to watch TV!”. Raise your voice – they won’t hear you otherwise – “I’m reading! I don’t want to be disturbed!” […]
Or if you prefer, don’t say anything; just hope they’ll leave you alone.
