At the drop of a hat

Stopiais i wrth yr afon y bore 'ma oherwydd syrthiodd fy het o fy mhen tra ro'n i'n seiclo.  (Wel, mae'n esgus da).  Roedd y tywydd yn heulog ac roedd cysgodion rheiliau ar draws y goeden. Ro'n i'n meddwl y byddwn i ymuno â nhw.

I stopped by the river this morning because my hat fell from my head while I was cycling. (Well, it's a good excuse). The weather was sunny and there were railing shadows across the tree. I thought I would join them.
