I communicate with pictures a lot (gifs, photos/snaps, bitmojis, etc...) A friend asks "whatcha doin?" it's fun to reply with a quick snap of what I'm doing. It almost makes you feel a bit "closer" to other people when you can get a quick glimpse into their world. A quick snap of a friend cooking is greater than a simple "I'm cooking" text. But I don't necessarily need or want to save that image (or really even that text)
