The Key describes something significant happening, or a twist of fate/solution. Combining with the Letter, I see significant news, important documents, or as Sylvie mentions in her book “The Lenormand Oracle“, “Life changing news”…
This is somehow connected to telephone calls, or discussions……….or to do with a relationship/a couple (Birds).
I can think of 2 things that happened today that would fit the bill for this:
1) my husband was on the phone trying to locate a very important document for his legal case, which he thought his former lawyers might still have. He was eager to be able to share it with his present lawyers.
2) we received a phone call from his business partner, that a significant deal should actually pay out this week. If it does, then our lives will change dramatically for the better.
Knowing that draws can stretch out for quite a few days, I will try to stay alert for other events that might correlate!
