Girls opinion: does this girl like me or think i'm a creeper?

so i was in the hallway and this girl ped me and she took a quick glance at me (she was walking wt friends). but when she got ahead of me, she kept turnin back and lookin at me (i kept looking away just so she didnt think i was looking at her *** [which is nice by the way]) and then today i ped her again and she glanced at me again and i turned around to go the other way and i caught her turning around to look at me again. i know she doesnt think im a creeper b/c i was sittin in the bleachers in gym and her and a couple of friends came and sat behind me. so i would think she would avoid me if she thought i was a creeper right? people have told me im good looking and all so what does this mean or does it mean nothing?
