Maybe she was referring to a Snapchat repurchase or getting cranky if you have forever Snapchat? That seems to be an ongoing source of disagreement. I wouldn't like someone telling me the date I'd last visited, and it doesn't seem like a wise business strategy (unless it's more in an I miss you tone as KK suggested).
It has nothing to do with that.
Seriously wishing I hadn't bothered posting this with all the ridiculous assumptions being made. Just let me have my vent.
