Today is a sad day for me, as my friend Mark is heading back to San Francisco. We have had a great time hanging out the past two weeks (I can't believe two weeks have gone by already!). You never know if your friends are good travel companions until you actually go on a trip together, but we got along really well.
I am really going to miss him.

What are you going to do, now that Mark is going back to SF? Does this mean you are looking for another travel companion? One who is about 3 1/2 years younger, female, cute, smart, adventuresome, related to you?!?!?!?!?!?!? hehehehehehehe
Love you!
