Mimi's Straw

I'm working in DC this week. I brought a Nalgene with me, but forgot to bring a straw, and since it's got a wide mouth, I generally find that despite being an experienced drinker, I tend to get water all over myself.

So I said outloud from my cubicle, "I need a straw". Always helpful, Mimi said, "I have a straw" and she passed a green Starbucks straw over the partition.

I looked at the straw and said, "is it used". She said it was but that it had been washed.

Three days later and I'm still using the straw. The question is: who gets it next?
