Going to a movie alone is one of the least awkward things

I agree

I can go to the cinema, to a museum and travel all over the world alone, i have no problem with that and i prefer it.

But i could not go and eat alone at a restaurant, that is the one thing i can not do alone.

I just go and buy takeaway and go back to the hotel room and eat there.

I just pretend to be a food critic…

do you read something while you do eat out alone, or use your phone or do you really just eat and focus on eating only?

Movies, sure a few times. Restaurants, I just get takeout. It's simpler.

I've never had a problem or felt awkward about going to the movies or to a restaurant alone, even when I was a kid.

As a single child, when my friends weren't around I found ways to entertain myself, even if it was just walking around the city and visiting the various 5&10's and department stores. If I had the money, a quarter in the fifties, I went to movies on my own and often remained after a Saturday matinee to see the adult feature even though the gang had gone home. Wound up watching films like Butterfield 8 as the only kid in the theatre while the usher (remember those?) stood by and scratched his head.

It was nothing to me to sit at a Woolworth's counter alone and order a hamburger and coke. For years I carried a paperback book in a coat pocket and read while waiting for my order in a restaurant. Never thought it was odd or paid attention to those around me. I've always been able to enjoy the relative solitude in my own space, and that has carried through to today in my late years. 

And in case you are wondering, no, I'm not a hermit or old fogie. I've been a member of the theatrical community since high school and completely comfortable in the company of many people or alone with my own thoughts. 

Movies as a social thing I always found overrated, though it probably takes someone a few times to realize that.
Restaurants alone isn't that strange unless maybe it's somewhere far to drive to or a very family oriented place. Most places nowadays have bars to sit at which is actually more welcoming for soloists.

This reminds me of using stalls in a public washroom. When I'm at your house, do I piss with the door open?

Back when I was single in my 20's and 30's I did both things alone. The only thing was, I usually went to matinees of movies, or late afternoon/ early evening shows. I even went once on a Saturday night, and it wasn't awkward. No one ever said "Are you alone? What's wrong with you?"

I used to go to diners and eat dinner and read a magazine. It was great after a long work week. I went after the lunch crowd and before the dinner rush. I was at one diner and a few servers said things about me being alone, and that made me feel funny. So I found another place, where the staff didn't mind that I was alone, they were happy to have me there.

Now I'm 65 and been married 28 years, movies are expensive and we are too tired to go out to eat.

I always prefered going to see a movie alone.
