People are weird. I can't be the first person to tell you that.

But mostly it's expensive.
So now, I always have the volume up. It's not generally a problem, because most people call my home number. My cell phone actually rings, but only at church, or during the movie, or anytime when silence is required.
Feel free to give any character you want, that random quirk.
I've had characters always have to wear gloves. I've had characters always have different color band aids on all if their fingers, or characters who sing in the car, or always walk around barefoot, or who always have a deck of playing cards in their back pocket, which they like to shuffle when bored, or nervous. Characters can send spam emails of kittens, or compulsively check Facebook, or to see if they have any text messages. Characters can wake up early to do yoga, or have five alarms, because one just doesn't cut it.
Do these habits further the plot. No. Do these quirks give insight into the character, not always no. But they do make the character more interesting, more remarkable, and most important, more real.
Think of Nynaeve, from Jordan's Wheel of Time, how she always pulled her braid. These quirks can be a tell into a characters emotion. Or Brad Pit's character in Ocean's eleven+ who was always eating. Every scene. Eating something. It could just give the character something to do.
I never mentioned why she always wore gloves, but all the clues were there. To someone who was paying attention, these little quirks added depth to the character and to the story. But if they didn't catch it, it didn't change the plot. It was also cool, how at the end she was married and didn't wear gloves.
That quirk told a story. It told her story.
Plus it's fun, and a way to use your people watching as a way to deepen characters. Quirks can be borrowed. And thank heavens, in real life, people are weird.
