This is much like the last post, only more specifically about those unexpected acts of kindness, as opposed to those you fully anticipate.
He offered his seat, carried your bags, took the check at the restaurant… He doesn’t appear to be flirtatious, either. How in the world should you respond when he performs such unexpected chivalry?
Say, “Thank you”.
Don’t hyperventilate about the fact that he did something gentlemanly for you! It was neither an offense to your abilities, nor a proposal of marriage. Stay calm.
This goes for any unexpected good deed, really – whether performed by a gentleman or a lady. If you’re life is remotely like mine, you should slow down and realize how many genuinely nice people surround you. This time, don’t take them for granted. Thank them.
