My grandparents have a caravan at the Baltic see where they basically spend all summer. This, in my view, is good for them. They get to be in nature, which should be good for their health, and they seem to have a more active social life there than at home, which is also good imho. Of course renting the space costs money, and quite a bit at that, but as far as I can tell its totally worth it for them.
In addition, my grandma likes to buy stuff on teleshopping channels - stuff like lotions, jewellery, clothing and candles. And while I don't particularly want to get involved in their choices - its their money - I feel this isn't adding nearly as much value to their lifes.
You can probably see where this is going. Every year, the choice to continue caravanning is in jeopardy because "it's too expensive", while the shopping goes on basically without interruption. When trying to talk to her about it, you'll hear things like "it's just a couple of Euros", apparently not realizing that this adds up if you order every other week. Also, my grandma gets quite defensive and feels being harassed when people disagree with her.
How can I make this a more productive conversation? I don't want to tell her what to do, I just want her to be more deliberate in her spending, and try to convey my sense of how much value both choices add to their lifes. How can I talk to her about it without seeming to intrude into her choices or questioning her judgements? (Of course, to some extend, that is what I'm doing, but with the best intentions.)
