Why the reluctance on going to a movie without the company of another?

Regardless of age, there are some things people hate doing alone. Whether that be eating dinner, going for walks, traveling, or heading to a bar on Friday night, they can't stand the thought of going about these activities by themselves. While I can understand this to a certain degree (except for walking/exercising), since most of the before-mentioned activities carry with them a social element, I can't understand this with regard to going out and seeing a movie. That may be different when seeing a movie at home, because the setting allows for more flexibility as far as time, socializing, and intimacy go. However, if you talk much at a movie theatre, people around you will likely complain, and there's a chance of getting kicked out. The same is true if you are too intimate with another during the film. So, why is it many are reluctant on going to the theatre by themselves? Like if they saw the film with another, there would be minimal conversation and minimal physical contact during its proceedings. Also, there wouldn't be any need to compromise on the film selection. The person could go to the film he or she really wanted to see - instead of opting for one which both people kind of wanted to see.

Maybe it's because I recently got out of a fairly long-term relationship and I'm slowly coming to terms with that reality, but since the break-up, I've gone to see two late-night films by myself, and while I was hesitant about it the first go-round, it was a much more relaxing experience the second time through, and I have a hunch it could be the start of a Sunday-night trend. Regardless of what others may think or say about going about such an activity solo, I think it's kind of nice. I tend to enjoy films which aren't in-line with most people's tastes anyway, so I can see what I want to see, not worry about whether or not others I'm with want to see it as well, and enjoy one of my favorite art mediums void of any distraction. 

So, if anyone out there is tentative about going to the theatre by yourself like I was a couple of weeks ago, I'd recommend giving it a try one time. Like jogging, seeing a movie solo allows you to temporarily get away from all of life's stresses and problems, relax, and enjoy something you love. Last I checked, there was absolutely nothing wrong with that.
