We have had a cold of sorts traveling around our house. First Miss L was struck with fits of sneezing, followed by a goopy nose. Then Steven was complaining a bit. Then, it was passed to Mr. B.
He seems to have held onto it a little longer. And, for good measure, added a cough.
In fact, since Sunday he has referred to himself as having the "bless you's".
I think this fits. Please feel free to take this and run with it. In itself the "bless you's" sound much more appealing than just a plain ole cold.
