How to play a sound to only one person?

Sooo... I need help, I got a GUI button, I made it play a click sound when pressed (And all that other code that makes it do what it was ment for, but ignore that.) So, how would I play that sound to only the person who clicked the button on the screen GUI?

function onClick()
    script.Parent.Sound:Play() -- This is where I needed help!.....
    script.Parent.Parent.BadgesButton.Visible = false
    wait(0.07)
    script.Parent.Parent.InfoButton.Visible = false
    wait(0.07)
    script.Parent.Parent.HelpButton.Visible = false
    wait(0.07)
    script.Parent.Parent.UpdatesButton.Visible = false
    wait(0.08)
    script.Parent.Parent.PlayButton.Visible = false
    wait(0.1)
    script.Parent.Parent.Title.Visible = false
    wait(0.1)
    script.Parent.Parent.Parent.UpdateMenu.Visible = true
    wait(0.06)
    script.Parent.Parent.Parent.UpdateMenu.BackButton.Visible = true
    wait(0.06)
    script.Parent.Parent.Parent.UpdateMenu.TextLabel.Visible = true
end

script.Parent.MouseButton1Click:connect(onClick)
