Unpopular opinion time: I don't particularly enjoy my birthday. I dislike the attention, the fuss, and yes, even the gifts. Cake is welcome (because who doesn't like cake?) but in most cases, I want to hide under a blanket for the entirety of the day.
There is, however, one exception to my allergy to presents, and that is in the case of experiential gifts. By that I mean instead of buying me something, take me somewhere. Let's go do something! Doing something fun on my birthday and making amazing memories is a much better celebration than any gift that could be given.
That fact is the very reason why I chose to go whale watching for my birthday!
