Send a snap! The photo will be low quality and you can't get a "like".
But you sent it, and that's the point. If it had been a text you might worry your meaning was lost. If it had been an instagram, your employer might find it ten years from now.
But you can't regret the snap, at least not for more than a day or so. You probably won't be able to remember it three days from now, and your friend certainly won't remember it three weeks from now.
The friction is gone, the worry is gone, and that's why you sent the snap.
