Make a part destroy locally?

I know the title may be a little confusing, so let me explain further.

I'm a beginner scripter, and I'm trying to practice making scripts run on the client, but in a way that it only plays for the person who activated the script.

So, what I'm trying to do now is make it so that if the player touches a red part, it destroys the blue part next to it, but ONLY for the player that touched the red part. (It appears for no one else.)

I thought all it would take to achieve this is for the LocalScript to be in StarterGui, but that's not the case. Help would be appreciated!

Here's my script right now.

--LocalScript inside StarterGui
workspace.redbrick.Touched:Connect(function(hit)
    local humanoid = hit.Parent:FindFirstChild("Humanoid")
    if humanoid then --Checks if the person who hit was a player
        workspace.bluepart:Destroy() --Destroys the blue brick when the red brick is touched by the player
        end
    end)
--(I want the blue brick to destroy only for the player that touched it)
