Grateful I'd say!

We sat in our garden and watched the sparrows coming to the feeder then flying off soon after inspection. They did not like the menu of suet/mealworm pellets. To satisfy them (after all they do entertain us) I put out a mix of mealworm, pellets and nuts. 
My 2 pictures (collage) seem to show mum showing indignation before the  swop of food, and in the second-saying thank you.
My imagination but pictures do tell a story.
