A sign in my friends' apartment building, about upcoming office closures:
(Small print) Office will be closed on Dec x due to all staff meeting
(Large print) THANKS FOR COMING!!
(Small print) The management wishes you happy holidays!
Er, huh?
Also, I did not catch that the iPad autocorrect changed my MIL's name to "Trash" in several emails. Fortunately this was pointed out to me before I ever emailed her directly! (FTR I love my MIL, we have a great relationship.)
