Some homesickness, but mostly lonely. She's there by herself, gets the touristy stuff done pretty quick, no work to occupy her time...it's gotta be pretty boring at times. She was staying at a place with a crappy internet connection and just about went nuts. She's been traveling for almost 2 months now and I don't think she's ever been alone that long before. Whenever she was lonely where she worked she could hop on a train and go to her hometown for the weekend, but now she's kind of stuck out there by herself. I think also she's realizing how much better it is traveling with a loving boyfriend than traveling alone.
