If they're being nice to you, its the right response.
If they're near you but not bothering you, its friendly.
If they're glaring at you, it means you win the argument by being happy at them.
If they think you're crazy, then they need to sort out their own lives and start smiling more


I find I scowl at people in the water (park, pub, high street) when in fact Im just squinting into the sun or focussing on something, so smiling all the time lessens that effect
