Is OTHER wrong in the post ? POST : In May 2013, my husband and I agreed to let my then 18 year old sister live with us while she went to college. We are both 10+ years older than her and worked two jobs while going to school so we know how hard it can be. We told her she had five years max to get a degree and move out. No rent or utilities were ever charged, she just had to buy her own her personal items like toiletries and snacks. A year ago she informed us that she would not be graduating before the five year mark so we gave her 6 more months til Jan 1st 2019. She did graduate in December!!! However she is still here and avoiding us at all cost. Locking herself in her room, ignoring our repeated knocking on her door/calls/text, and sneaking in and out the back door. She hasn't spoken to either of us in 3 weeks. I don't think she has any place to go or any money saved but at this point I don't really feel sorry for her. I feel like I'm being used. I've called and made an appointment for a locksmith to change the locks on Mon. My family says it's terrible to just kick her out but none of them are willing or able to take her. Even my friends are saying I can't kick my own lil sister out on the street. Everyone says to give her a few more months but we already extended the deadline once. 

TL;DR Agreed to let lil sis (23 now) live with my husband and I for free for 5.5 years until 1/1/19. That day has passed and she is still here and avoiding us.  I have scheduled to get the locks changed on Mon. Do you agree with my family and friends that I can't kick out my own sister? AITA?
