For once you have the opportunity to make yourself useful to Miss Lizzy. She's had a long day and she needs a cigarette. She's hanging out in her garden, there aren't any available ashtrays. But there is your mouth. Lizzy allows you to get close enough to inhale her second-hand smoke and take all her ashes in your mouth. Aren't you lucky that you are the one chosen to be used as her ashtray? If you do a good job, meaning you swallow every ash, she may even allow you to swallow the butt.
