There’s this girl in my college class, who’s my partner, I thought she was cute but didn’t really think much of her. All of a sudden she started giving me cold shoulder and get angry when I asked her for her notes like I usually do. I kept my cool. Today I complimented her; however, she didn’t take it so well. When in class she was constantly touching my feet and trying to get my attention. Then towards the end of class she kept giving me the cold shoulder again. My question is how do I know when she’s interested?
