I was given a rose today at work! I am not sure whether this is an actual thing or not, but when I got the flower I was told "Happy Neighbors Day!" I said thank you, but they were in a rush that I didn't have time to ask them about the "holiday". So of course my next step was to google it. I couldn't find much on the subject, but I really appreciated the flower, anyway! Does anyone out there know anything about this day??
