This is a short story about a chemical reaction. The reaction is a double replacement. The chemicals we are going to use are Ca(Calcium) Cl(Chlorien) Na(Sodium) OH(hydroxide). And the story of these chemicals start like this...
The four arrive, and the bass is thumping and Camery and OH where ready to move and grove. But Cole and Natily where not so sure about dancing any more.
So by the end of the night the new make up of the two couples are: Camry and OH; because they liked to dance. Natily and Cole sat on the bench and shared a shake. (CaOH + NaCl)
