Does this mean she likes me?

I was on the bus and all of the sudden the girl I have been talking about in my last 2 posts sat next to me. She started to talk to me and we talked for a little while. Eventually I asked why she sat next to me and she said there was no other place to sit on the bus. I decided to see if she was right and there was 5 seats that were open behind me. If someone would tell me I would deeply appreciate it.
