I wasn't expecting this, by when I woke up this morning on my birthday, my boyfriend informed me that he planned a trip to Califoria for us and that we are leaving today!

I would be so excited!

Same here! It was a wonderful idea, and very impromptu!

Hopefully everything goes really well for you and happy birthday!
