Everybody is right here. The annealing aligns, or mis-aligns, I forget which, the copper molecules whichh allows them to be bent. Environmental changes like bending the wire or going through temperasture changes will shift the molecular struture and harden the copper. Thus, annealed, unused wire going trhrough time and temperatrure changes stiffens the wire just like working - although much more gradually.
