Nagging sister!

I called my family in Cebu, Philippines. I talked to my sister Helen and she told me that my other sister, the one who lives in Germany (Beth) and had an argument with my mom two days earlier! My mom got mad at Beth because she pressures them too much. Beth wanted them to plant more trees, vegetables, plants and flowers. My mom told her that they already planted a lot and that there is no more space to plant more! Then Beth told my mom to tell our sisters-in-law to plant more flowers. My mom replied saying to leave them alone and let them decide what they want in their life. My mom told Beth that she heard my brother and his wife talking about finding a new house far away from her so they will no longer have to hear all the nagging from Beth. They feel that every time she calls she gets angry and has something negative to say to everyone. They feel like Beth manipulates their lives!
When Beth heard that she got angry again and threatened to not go home to Cebu anymore! She said she would never help again! I know Beth is out of line sometimes and can be too much for our family! She said a lot of hurtful things to us but sometimes I can’t blame her. She is controlling but she has supported us a lot! Although she loves to nag she loves us and tries to help as well! Hehehe.
