touch should not updated `updated_at` on destroy in Rails3

Question

I am working on touch in Rails but facing on issue here.

class User < ActiveRecord::Base
  belongs_to :company, touch: true
end

But I want this should not update the updated_at of company model only when I delete the user but other case it should be. How can I do it?

Or

Is there any way to restrict this in destroy. Because I don't want it on destroy.
