Whatever door is relevant to you both walking through, please do not lose sight of this simple but often overlooked act of kindness.
This is a general statement because it applies to many facets of the evening.
While the origins, again, are from a time not like today – the idea is the same: Protection. You may be saying to yourself: Come on, nobody does that anymore. A good morning text first thing doesn’t just say “good morning” – it says “you’re the first person I thought of when I woke up today.” Small romantic acts aren’t just for the “honeymoon phase” of your relationship. At the end of your date, especially early on in the relationship, walk her safely to her door.
This is especially important if she lives in a city.
Times change, and along with them – social norms change. Acceptable behavior changes (sometimes for better, sometimes for worse), and basically, well, everything changes.
