<human>: So here it goes. Today was the last day of a class I have with this girl. I had always thought she was at least might've been a little bit interested. 

Anyways, since it's the last day of classes I'm walking with the girl I'm interested in and another girl. I asked them if they wanted to go eat something together. The girl I'm interested in says "Sure, I guess I'm kinda hungry" but the one I'm not interested in had to take a rain check. 

Since this girl can't go, the girl I'm interested in just says "I guess I'll go home, then." I was pretty disappointed by this, and it's been kinda brooding in my head for a bit. Does this mean she wasn't interested at all? If she was interested, she could've still went out to eat with me despite her friend bailing. Then right before she part ways she ended up giving a little spark of hope by saying, "Well, what are you planning to get?" and I tell her where and she remains silent until we part ways. 

I guess I'm just a little disappointed since the person I thought could've been interested kinda shot down my indirect attempts at getting to know her. I don't have her number, but I do have her email. I could always take the passive way of asking her out by email, but at this point is there even a point considering she kinda already said no to being alone in person?

Provide a brief overview of the text.
<bot>: Girl I thought was interested in me. Asked said girl + her friend to go eat, her friend can't go, so girl I'm interested in decides not to. Is she not interested in me after all?
