Concerns of An Old Duck

I hope you don't find this intrusive, Or forward in any way, Where are you, Rico? Are you on Holiday? I hope you are on Holiday, And trying to give your brain a rest Writing so many fab limericks, It must be a cranial test. Maybe, you are tired, I hope you are not ill, Is your brain temporarily unwired? That would be a bitter pill, To swallow, especially for one so bright, I miss your contributions, To PS I sincerely hope you are alright!
