I am still amazed at how some people can cause so much damage. There is a reason why I don’t generally let my friends or family borrow things, & that is because some of them treat it like trash. If you plan on borrowing something from a friend, treat it like it was your own device. It’s sad that I even have to say that, however it’s because I am speaking from personal experience. Sometime back my acquaintance was going on a camping trip. They didn’t want to go on the camping trip without some form of heating & cooling, so they asked if they could borrow my portable cooling system. I was a little bit hesitant, since it is such an extravagant device & I didn’t want anything happening to it. But I decided that I should trust my acquaintance & let them have it. When their camping weekend was over, they returned the portable Heating & A/C unit, & it was in horrible shape! It was covered in mud, for starters. My acquaintance nonchalantly told me it started raining so the portable a/c unit got a little muddy. A little? It was particularly not a little, it was covered in mud. Not only that, however it was clogged as well, particularly from all of the leaves & debris getting stuck inside. I had to bring the portable air conditioner to a Heating & A/C business & have them service it. It took a ton of cleaning & it still isn’t functioning as good as it was before I let my acquaintance borrow it. I should have made them spend money for the damage, but I didn’t. Next time though, if someone asks to use my portable Heating & A/C, they are out of luck.
