Should you down play how well off you are for the benefit of others?

We're currently moving and while we're waiting on paperwork and everything to finish up we're staying at my husbands aunts. She's out of state and needed someone to watch her house for 2 weeks while she's gone, so it worked out for all of us.

My SIL and her 3 kids live right down the road with my FIL in the house my husband and her grew up in. My SIL is 40 years old and has never worked a day of her life, has always lived at home, and depends on my FIL to pay all the bills. He's on disability and only gets $700, so they are barley getting by even with their $600 a month in food stamps.

While my husband and I have worked 40+ hours a week since we were teens, and have saved up for everything we have.

Anyway while staying at the aunt's house we brought SOME of our stuff with us. Such as our laptops,my son's Xbox & his TV, and of course our cars. While staying here we told my SIL we didn't care if her kids came down and played with our son (their all around the same age). Of course at some point they wanted to play xbox which was fine we have plenty of controllers and multiplayer games.

Later that night when they went home my husband got a call from my SIL that was basically her saying we made her kids feel bad because they don't have the same things as my son. And she felt like we were rubing the fact that we are better off than her in hers and the kids faces. That there was no reason to have our "nice ass cars" parked out front for the whole neighborhood to see etc etc.

Our intent wasn't to rub anything in anyone's face, we just wanted our stuff with and were being nice to our nieces and nephew.

So my question is; in situations like this should you down play how "well off you are" for the sake of a family members feelings??
