holding my tongue

I'm chilling with Peter and Chris, the embassy brothers productive.

Peter: That was great. Me and Thomas found that.
Me: Thomas and I. No one speaks engilsh here.
Chris: Well people make that mistake in America too.
Me: At my old school, we were all sort of pretentious and we'd correct each other's grammatical errors. I've been holding my tongue all year. I can't do it anymore.
Chris: So... up until this point... you've been quiet?

Fair enough. I'd been holding my tongue about grammatical errors. My tongue had been pretty unrestrained regarding almost anything else.

Well that last sentence sounded strangely suggestive-slash-creepy.

Love always,
Clara
