Had the flu recently, and friends dropped off some food. In the cheaper ziploc or glad plastic containers, not the more expensive Rubbermaid containers. Really appreciate the gesture, but here's my dilemma: should I
1) keep track of who brought which containers, and return them to the rightful owners,
2) toss them, or
3) buy a new set for each friend, so that they are not short of containers?
What would you do?
