it was a day of bright sunshine , hot sand , tuna fish sandwiches that yaeko had prepared the night before , followed by ice cream cones ( alexandre brought these himselfon the house , he said as he handed them over ) , and lots of layers of sunscreen and cool tunes from yaekos new music player ( they shared a single pair of headphones , the left plug in melodys right ear , the right plug in yaekos left , their heads bobbing up and down in unison with the beach boys , one of their all-time favorite groups ) .
