SIR, - Houston you have a problem. We noted your potential problem whereby you had scheduled your black and green capsules to rendezvous at the same place on the same date - a potential disaster! We also note your revised schedule on the two calendars.

We would like to suggest that future schedules only consist of one calendar. The black capsule rendezvous dates/weeks should have white letters on a black background. The green capsule rendezvous dates/weeks should have white letters on a green background.

Then we only have to remember that other recycleables are collected with the green capsule unless we cannot recycle them, and then they go in the black capsule.
