The Sign

I've worked in my home office for the last five years. I like my work although at times I miss the office communication with collegues.
Over the last two days, strange things have occurred near my home. Yesterday I saw a plastic package (which is circled) in my backyard on the third floor, the package was black. I admit I didn't pay much attention to it at the time. But today I saw another flying package... Everything was the same as the package was yesterday, except that this time the package was white! What is it?! Definitely it's a sign. But what it does it mean? Why was the package today white? Maybe it means a change for the good? Or maybe it means I should leave my home and find a job in an office? I don't know... But the one thing I do know for sure is that tomorrow I will be looking out my window.

P.S. It's just the joke about my interpretation of the "sign", but the story of the two flying packages is real :)
