Leaving on an Airplane

Today my twin, Luke took off from Milwaukee International Airport to go to HAWAII. He is going there with his girlfriend and her family. It is his first big trip without our family and well without his twin. I have taken several trips without him so he has been itching to go and take a trip. He was planning on doing some kayaking and hiking while there so it should be a blast. Im sure he will keep in touch with me for the week while he is there but its weird to think how we have separate lives even though they have always been so tangled together.
