When employers tell me they prefer married men, and encourage their men to have homes of their own, because it makes them so much steadier, I wonder if they have any idea of all that that implies.
It's often just enough to be with someone. I don't need to touch them. Not even talk. A feeling passes between you both. You're not alone.
I don't know if it's harder but when you're playing a real person you want to honor their memory - even if they're a criminal or someone that the public loathed. That can be challenging.
