There was a photo in a club competition last night. It was an image of a lovely little girl in her school uniform in front of a huge chalk board with writing on. The thing that stood out immediately was the word "photo's". This is annoying enough but the inconsistency bugged me: there were other plurals and none of them had an apostrophe.
My phone does like to make me look like an illiterate fool though; not only does it insist on putting apostrophes where they shouldn't be or removing them from where they should, it also replaces whole words after I've typed them and quite a lot of the time I miss them. I might want to write, "I'm in the house," for example, and it will change in to on for no apparent reason.
