Do you use an oxygen tank?!
Question:
Do you use an oxygen tank?
Over the past few weeks my aunt and uncle have noticed that their carpet is getting darker for no reason. The only thing we can figure is that my uncle recently started taking oxygen (my aunt has been using it for a long time). Could the doubled oxygen in the house make the carpets darker?
Answers:
My dad had oxygen for 10 years. His carpet never got darker. The only ways the two could be related are: 1)the delivery guy has a lot of dirt on his shoes; or 2)the wheels on the oxygen-tank cart are dirty.
