Mom gets annoyed with bad spelling on signs. PlusOne was particularly annoyed with this one because he plays the Cello. It isn't "Celloist," it's "Cellist." So when they were together last weekend and saw this sign, they had to stop to take a picture.
That wasn't enough. "I feel the need to fix it," said PlusOne.
So he did.
I guess the world will spin a little more smoothly now...
Update: PlusOne put the extra O in an inconspicuous corner of the sign.
