It's strange which character traits people inherit from older generations. Of everyone in the family, dad was the one who could least tolerate tepid food. He often asked you to heat his food a little in the microwave, when no one else was upset by it. He claimed he couldn't eat in IKEA because they never served the food hot enough!
Recently Amaia has started to go down the same route. If she eats too slowly and her meal cools down too much we get her famous 'I just can't like cold rice!' and she does everything in her power to make us heat it till it is piping hot so she can continue to enjoy it.
