How to delay a function? Easy? not use wait()

so I made this door script that plays a sound when its moving and when its closed

I want to make it so when the door closes it makes a "Thud" sound, but I need to delay the thud sound by 1 second because it plays too early

function open()
			local finish = script.Parent.PrimaryPart.CFrame*CFrame.Angles(0,math.rad(90),0)
			sound:Play()
			click:Destroy()
			thud:Play() -- how to make this play 1 second later?
				for i = 0,1,.01 do
					local cfm = script.Parent.PrimaryPart.CFrame:lerp(finish,i)
					script.Parent:SetPrimaryPartCFrame(cfm)
				wait()
			end
			wait(1)
			script:Destroy()
end

Make the thud sound play 1 second later without stopping the script. That is without adding a "Wait()" function.

Nevermind found the answer myself

delay(.8,function()
            thud:Play()
            end)
