First you write captions with one pic, then go for two, now with three, are we to expect quadruples, quintuples and so on?

I’ve already done a quadruple caption. If you want to count pictures per story, then “Reunions” was a sextuple caption. But no, I don’t plan on throwing in as many pics as possible–I use as many as fit with the story. I wish I could use less pictures actually, but the stories I post with no pictures at all get almost no notes. Tumblr prefers visual mediums I suppose.
