Well, hey! Just look at it like this, you're doing a really great & nice/wonderful thing (for them). As without your generosity and hospitality (?) - they'd be in much more difficult & gravely uncomfortable circumstances (unless other significant changes were implemented). So while the sacrifices seem to be reaping fewer rewards on the surface, perhaps they will pay-off later on, or in the long-run! You know, with the benefit of hindsight, and when they can look back and feel or realize how fortunate they were to have had that offered & open to them. Also, behavior/or habits (such as that which you've been discussing) are hard to come-by when it comes to alterations; or change(s). So don't beat yourself up for being unable to make much progress in this regard. Hopefully, things can begin to improve at some point, you'd still like to hold out hope & believe. Though I don't know if that change would have to come from within - when it comes to say, motivation? It's pretty hard to let the small stuff/or things fly, when they add up and compound, or deliver a cumulative effect. Which I know the reason why it bothers you so much, or is so troublesome, is the meaning it may communicate, or the message that it sends/& delivers. In terms of how much they care, or think of/about treating you. In terms of respect & all else: only thing I can say is this--at that age, it can be difficult to summarize life in that moment & let them crystallize or allow them to formulate clearly, the dust to settle as it were, such that they see the forrest for the trees, or have some kind of proper perspective placed on or upon it (the situation). In other words, a lot of these little mini-negative behaviors and lifestyles are perhaps/probably - possibly a function of their "unhappiness," with things in their own lives. And more-so a statement of impact of that (their dissatisfaction w/life) & less about what or how they feel about you. They're sort of numb to being able to think of things in that way yet. As in right now. They're too self-centered & pre-occupied with their own selves, and their own issues. Than to be focused on how what they do (w/their laziness, etc.) can be having a profound detrimental impact on your own happiness, and otherwise - overall health. As I said, hopefully it's a stress that pays off. And one day you'll look back & feel good about the things you had to stomach or swallow. Maybe too, they will reach that stage or state, where they can realize this too. And if so, they can think to be troubled or bothered enough, to pick up the phone and tell you so or send you a nice, warm-hearted, "Thank-You" card... with 'blank-checks' in side~


We can hope & dream: can't we!
