There is this girl I met from school and her aesthetics and overall used to be so diffrent than mine; she prefered bold and more sassy now its almost like whatever I like she likes too...I wouldnt mind this at all idc about style that makes us twins! butttt... She triees to argue with her partner when Im arguing with mine and tries to get me to argue while she argues with her partner? Suddenly wants the same career and changed opinions about her parents for them to be exactly be mine! I cantt tell if Im overreacting orrr if this is kindaaaa weird-
