Here's how to duet on TikTok.
Open TikTok and find the video you want to duet with.
At the bottom of the sidebar menu on the right,
tap the sharing button.
It looks like an arrow pointing to the right.
At the bottom of the "Share to" menu that pops up,
tap "Duet."
Tap the red button at the bottom of the screen
to start recording your video.
Yours will appear on the left,
and the other person's will appear on the right.
When you're done, tap the check mark
to the right of the recording symbol.
Add any text, stickers, or effects you might want,
write up a caption,
and post.
"My mom's always talking to me,
telling me, like, all her secrets.
She has no idea I actually understand her.
'cause if she did, I would, like, have to listen to her.
No way."
