Miss having a wide choice of films, sometimes.
Have been to cinemas alone, there is a cinema in London, adjacent to the Swiss Centre (Trocadero, Picadilly Circus area) that showed French and other non-anglophone films.
I saw many there on my own, amongst those I remember was a Belgian film titled "Man Bites Dog".
Also attended many classical music and flamenco concerts on my own... with some chemical friends, mind you.
