Well there is a stage created by Erik Erickson and it is called Integrity vs. Despair. The older you get, the more you look back at the things that you never got to do. Maybe your sister was never in charge when she was younger. Although she, her twin sister, and her mom are somewhat alike, maybe she was the one who was not in charge as much as her sister and mom. She might be letting it all out now, because her feelings were so bottled up then, as a child. Now that she is an adult, she may feel as if she can do anything; she may feel as if she is on top of the world and her mom and sister can't tell her what to do now. This stage is mainly for late adulthood, but the stages DO overlap.
Another reason, she might not have said thank you could be because maybe she felt offended when you changed the filter.
Hope this helps!!!!! :)

I'll take my ball and go home. by: Thomas
that's a control issue. she feels undermined.
emotional skills are just that, skills. not everyone learns them.
except her as she is, and let her feel in control in her own home.
