1. I smile a whole lot speaking to strangers passing by our booth, knowing it’s more of a delight to see a happy face than a dull one, although I feel I am far too mature to be a hostess.
2. I smile a whole lot at my old acquaintance because I am really glad to see him although I may be misleading him to think how overall happy I am.
3. I smile a whole lot talking to my colleague from work, this energetic 10 years younger woman with a life style so different from mine, that I would hardly ever communicate on a private basis.

And the day turns out different from what I dreaded and eventually everything is fine and worth smiling at.
