Sometimes my friend will send me 1 snapchat but that 1 snapchat will be (for example) 53 seconds and in that one 53 second snapchat there will be multiple pictures with different captions (and sometimes a video). The only thing about this was it wasn't a snapchat story that everybody could view, I received it in my inbox and only I could see it. How can I do this? How can I send it to only one person?
