When a girl offers you a sip from her drink?

[Anonymous]

Stupid question, I know. But just curious that's all.
So, this girl offered me her drink saying it's nice and I should try it. I asked her if she would mind if I used the same straw she was using. She said she didn't.

Does this mean she is comfortable around me or likes me by any chance?

I don't drink after people but I guess being nice?
