My wife had an issue at first, then I think she spoke to one of her friends, because suddenly it wasn’t an issue, as it was “harmless”. If I mention a great deal on a light that I am considering she just says “buy it”. I suspect a friend compared it to drugs/alcohol/smoking/gambling and other harmful addictions which are completely foreign to me. We both know people whose lives have been ruined by alcohol and others who spend more on smoking than I do on lights, with cancer an issue as well. The only craving that makes me grumpy is if I miss a couple of runs or gym sessions, so as addictions go, one that has no withdrawal symptoms, health issues or side-effects other than cost is fairly innocuous.
