<human>: I am a guy, and this really cute girl walks past me fairly regularly as I walk to the train station and she walks to the bus stop and essentially we walk by each other.

I can't really just stop her and say "hi", because i think thats a bit odd and it will end with her awkwardly just saying back "ummm hello".
So what do I do? The subtle bump into her? Even if I do that I say sorry, she says sorry and we walk our own ways.

Any things you have done to get someones attention that has worked? Or any ideas?

Summarize the given text in a few sentences.
<bot>: Cute girl, walks past me most days, dont know eachother, how do I crack up a convo with her?
