Layla's birthday is next Tuesday- our weather is supposed to be lovely here- mild at least

I want to think of something special to do with her on her birthday (yes I KNOW she has no clue and for all she knows it is just a random Tuesday). She does not need anything and instead we will be giving to a yorkie rescue but i still want to DO something with her... any ideas???? I don't know why this is so hard.....
