Reading some of these stories makes be cringe and also serves as a reminder for me to not loan out my lights. The last time I did that was 7 years ago and I haven't done it since: I brought an HDS U60 with me while camping with friends, one my friends noticed the multi-levels and asked if he could see the light, I gave it to him, he then stood up, walked into the woods as he was "answering the call of nature":toilet:... He did his business, walked back to the camp site, then placed my light onto a picnic bench that he was walking by.
I watched as he did this and as he walked right by me without saying a single word or even giving me back my light. I was astounded. Needless to say, I picked up my light, went to the river to rinse it off :eeew: and ... decided then and there that I would never, ever again loan out any of my lights to anyone. Unfortunately, out of necessity, sometimes you need to ensure someone else in your group has some light so I have an older light - I don't mind losing - that I bring with me as a loaner.
