I’m talking to this girl on Snapchat and every so often one of my snaps that I send to her doesn’t go through, however it still says delivered on my screen. Usually, I’ll send another snap to her a while later (within 24 hours) and she’ll open it but won’t open the snap I sent before (which is how I know that it didn’t go through) or she’ll open both which is how I know she was airing me. I just want to know how long is a suitable length of time before I can send her a snap after I think my snap didn’t go through properly and also what to say on that snap...
