and while I realize that I am no where near perfect, I do find a few of these problems quite irritating.
The first that comes to mind is sign grammar and spelling. If someone is going to put time, effort and money into making and posting a sign they should be sure that it makes sense. I find signs that contain errors to be entertaining, and yet highly annoying. Some claim that I have invested too much time and thought in this- I fully agree.
For example:

My problem with this sign: the incorrect use of a simile.
In the statement says that “God is like Hallmark because he cared enough to send the very best.” It’s a wonderful thought, but it doesn’t make sense. Hallmark doesn’t care, and they don’t care enough to send the very best. Hallmark’s claim is that they ARE the very best, making a Hallmark customer the caring one.
In the context of this sign’s message it should read:
God is like a Hallmark customer…
Oh Steph, we really are two peas in a pod. That sign would irritate me to no end as well.
Really, all those church, “look! we’re accessible to everyone! And we’re witty!” signs irritate me. Say something you didn’t find at the bottom of an email forward!
