Why was she doing this?

So I was in dinner line at school and one of my female friends walked behind me brushing her arm against my back then we had a mini convo about our day next thing she was asking me if my friend had a crush on her. I was listening playing on my phone then she starts pressing her breast on my arm while asking me it then her friend was like saying her name then she goes in just asking him a question. Why was she all over me
