How to find the object being resized?

function onHandlesDrag(normal, distance)
    .Anchored = true
    if handles.Adornee then
        local delta = distance - previousDistance 
        if math.abs(delta) >= handles.Adornee.ResizeIncrement then
            local sizeDelta = math.floor(delta / handles.Adornee.ResizeIncrement + 0.5) * handles.Adornee.ResizeIncrement
            if handles.Adornee:Resize(normal, sizeDelta) then
                previousDistance = distance
            end
        end
    end
end

As you can see i have put .Anchored = true because the first thing i want is the resized part to be Anchored but i dont know which part is being resized or how to find it...

Thanks for the help! :D
