I just read her message and I think I'm dreaming.
It's a couple with kids who is inviting us for dinner. Initially I wanted to invite them and other people and contacted her to ask about her schedule as she's a nurse with strange working schedule and suddenly she decided to host instead. Well, ok.
So I asked her what to bring and talked about a recipe I wanted to try that could compliment her turkey. And suddenly I'm seeing that she tells me to come at 15h and be punctual so we can spend more time together.
It's funny because they are not particularly punctual (not to generalize, but they are latin and it's not rare that they are at least 30 min late) and typically our gatherings were never so formal. I'm kind of turned off.
