Discrimination is no laughing matter. How often do you see Sikhs constantly being discriminated especially when it comes to flights? It's often. I wouldn't support our worst enemies going through some of the treatment we go through. And sometimes this discrimination effects non-Sikhs as well with many of women getting sexually harassed by the Christian airport security.
if it coming in from the road open windows which open swinging out with a closed top else small opening with net curtain in front to slow particle entrance wipe window sills every morning where most of this stuff will settle . No shoe policy helps a lot in our house along with outside rubber mats and inside door mats which are washable at all outside entry points. Those wonder mats are great. . Regularly hoovering the porch/hallway also stops grit and dust travelling in.
Not so much, but noticed this time of year too much dust accumulates even after cleaning. Just cleaned the window sills and was looking for dust removal techniques. Need to get some microfibre cloths again as tried with a wet paper towel and it wouldn't pick up.
