I have a very close relationship with my older sister, we are very similar in a lot of ways. In general I dont like people to call to the house with giving some notice. My sister is the exact same so I always text or call and would never show up at her house without her confirming that it suits. Despite her knowing this about me she has started calling up to the house unannounced, coming in the back door, knocking on the window etc....I hate confrontation but I decided it was the right thing to do to let her know that I would rather she text or call me before calling up. The text was fairly pleasant in my opinion as i love her and love seeing her. Well she seemed okay initially when I said this but has since ignored my messages and my calls. Don't know what to think and feel like shit...
