Oh, I get it, now. Interesting. It's so weird, though, I mean, the only reason I could think is that the person doesn't want me to know when they got it, but, by clicking deny receipt it goes off the tracker altogether. Either way, you can tell they got it. Unless they clicked on deny receipt accidentally. It just seems like with certain people, it happens a lot. I never even considered using it......if there are people that do use it, and, wanna share with me the reasons.....it could be enlightening for me! It doesn't have to be people that I chat with, and, it'll be kept in private. I'm just wondering why anyone would purposefully do that....
