The next time you watch TV check the commercials for any male character portrayed as a simpleton. How much respect does anyone (either gender) get these days?
Are there many folks here who actually expect their lights or tools to be left alone when there's anyone else living in their house?
Seriously, most children, neighbors, and spouses have the attitude of "Oh they won't mind, they've got so many..." They don't ask, they don't return items, and they think that every tool in the box is the same as the others (Ya mean ya shouldn't use a torque wrench to loosen a rusted bolt? Ya shouldn't use the sterling silver tableware to tighten a screw?).
Just because you have a set of tools or a few lights for different tasks they think they are all the same. Who couldn't better use that "replacement fund" money for their retirement or at least the beer fund? (Gosh, there are times I miss drinking).
Do NOT spend a lot of money on lights for the family. Buying most children or spouses their own lights or tools is just postponing yours going missing until they lose the one you bought them so you're out even more money. Being nice only goes so far. Being nasty gets you nowhere.
Is it any wonder the divorce rates are so high? Respect in the home is mostly a thing of the past. Keep your lights and tools under lock and key or on your person. Being polite doesn't work very often. I love most people but I do not trust more than a handful of them.
