Oh my gawd!!!!! Someone was watching over you and your house. I hope she knows enough to not smoke anywhere near the baby, or even in the house. Thank goodness for your planter and shrubs.....guardians of the porch!
Is the mailbox out at the street, down the driveway? That would be a “safe” place...nowhere is good, but that would be safe.
The mail box is next to the sidewalk in front of the house. This is where any future smoking will take place when they visit in the future.
