Small random memory that stuck in my mind. You were swigging down green tea while something I said (I forgot what) made you smile. Your lips curved up into a generous U and you couldn't drink properly unless you stopped smiling. But you couldn't, so you just tipped the drink awkwardly to your mouth as you smiled on. And then you said it's been a while since you last tried to smile and drink at the same time, and I was glad it was cos of me.
