You were having a lovely discussion with a tall, polite woman you encountered when all of sudden she seemed to burst into a rage and pushed you against the wall by your collar, her face contorted with a pained expression as she displayed frustration at the current state of affairs. Just as quickly she realises her regret and releases you, glancing away and rubbing her arm with some shame.

Sorry about that, I can be a little...protective when it comes to my sisters.
