When my husband and I worked at the retirement community I tried to do little things to make the resident's day fun or different. One of those things was to put a bit of food coloring in the carafes on the table. For St. Patrick's Day the water would go green. Some residents liked it...others did not. They thought it made the water taste funny. But it got them talking.
My husband doesn't drink water and eats very healthy food. So it was either coloring his tuna green or making green eggs. I picked the eggs.
His response? Gross! (But he was good enough to eat them). Perhaps I need to step away from the food color, huh?
