I'm a good singer, but my sis claims she's better. I KNOW i'm better. What can I do? Please help!!!

Just ignore her. I know it's hard, (trust me, I grew up in a house of 7 kids) but sometimes it's what toi gotta do. As long as toi have confidence in yourself, that's really all that matters.

But, if you're serious about proving who's better, toi could have a contest. Each of toi sing to a randomly selected friend/relative and let them decide. Or, if toi don't like chant in front of people toi could record yourselves.

There is really nothing toi can do if someone is being immature in that way. Ignore her. toi have nothing to prove.

Do a chant contest to know which one's better. ou record both of your voices chant and judge which one's better.

have a chant duel challenge her have your Friends and family choose

Just say "You know what! That is super mean whether I am a good singer ou not! How would toi like it if I called toi a bad singer ou a dit toi sing of key?"

Have a contest, and let who eva is watching decide! prove yo sis wrong and montrer off yo talents!!!!

Don't fret! No offence, but it's just a voice! It doesn't matter who's better, what matters is that you're both awesome in your own unique way!
