This might be a silly suggestion but when you are showered with this extra (and sometimes unwanted) attention, why don't you try inviting two of your pledge sisters along? Make it a group thing always inviting different pledge sisters each time. This could help you to bond with more pledge and active sisters and could turn you into the catalyst (matchmaker?) for forming bonds between your sisters. There is no reasen why this extra attention displayed toward you couldn't be redirected toward others with your help.
