So, there is this girl that I like. She and her best friend both liked my Instagram photo that i recently put up, but then afterwards her best friend put up a photo too. I have a feeling her best friend only liked my photo to get herself a like, but I'm not sure if I should return the like to her for fear of accidentally making the girl I like think I don't like her (which I don't want!). Should I like it or not?? (Sorry if it doesn't make much sense)
