E|--------------------------------
B|-----0-----0-----0--------------
G|-----1-----1-----1--------------
D|--2-----------2------------1--1-

when the text comes in play this:

   E           A                 
E|--------------------------------
B|-----0-----0-----2-----2-----4--
G|-----1-----1-----2-----2-----4--
D|--2-----------2-----------------
A|--------2-----------0-----2-----

  B                  E
