People used to worry that knuckle cracking would cause arthritis later in life. Scientists haven’t found evidence for that. Still, your sister may not realize that her knuckle cracking annoys you, so talking to her may help. At a time when the two of you are getting along, you might simply say “I’ve noticed that you crack your knuckles, and I wondered if you could try not to do it around me.”
Try to concentrate on having fun with your sister rather than focusing on her habit. If her knuckle cracking gets on your nerves, just quietly leave the room.
