There are a few that annoy me, but I can't think of a pacific example right now.

But I wish we could form a committee, from all English speaking countries, to coin some agreed gender-free pronouns.

"If anyone has a suggestion, he should post it here."
Oh no, thats sexist, it should read
"If anyone has a suggestion, they should post it here"
OOPs, "anyone" is singular, "they" is plural so that won't work. "If anyone has a suggestion (s)he ....."??

Someone, please coin some new pronouns.
