Well it’s not that it never happens, it’s just that it’s not particularly likely. Heat is disordered kinetic energy, so most often molecules won’t be traveling in the same direction.
from my understanding, water is typically colloidal, so it would make sense that there's no symmetrical bonding to adjacent molecules and that could easily lead to groups being evaporated.
