Yes. I've been to the theatre, restaurants, art galleries, museums and even on continental holidays on my own. I'm happily married and have lots of friends and enjoy all sorts of entertainment both with others, as well as on my own. Sometimes I like doing things on the spur of the moment and prefer to just up and go without too much discussion before my sudden urge dissipates. Also my taste does not always coincide with others, and although I do not mind joining in with friends' choice of entertainment, I prefer to just attend my own choices without imposing on others who are less keen. I don't have to compromise, as to what I see, what I eat, how long I stay, how far I walk, etc. Actually I do enjoy my own company.
