My dear....its not her hard to read.
Its you not knowing to simply ask and tell her direct.
It would have been easier, if you asked first and then action on
somethings.
Eg.....conversation: Dearling argh....your friends leaving soon.
Would you prefer to spend your birthday with them and I go fishing
and give you and friends some party space?
Then I come back, before they are gone, and we go celebrate some
more. You can choose to celebrate with me privately or wth them
along too, as a farewell thingy?
