I make no conscious effort to be tough, or hard-boiled, or grim, or any of the things I am usually called.
My wife will tell you it's the little things, like driving my boys to school on my days off so she can rest. We're not into PDA, but every time we end a phone conversation, we say 'sarang,' which means love in Korean.
There's no adventure in knowing the outcome of who you're supposed to be with.
