Unpleasantness of Cleavage Showing

Have discovered two unpleasant things about cleavage today, not sure why only just discovered them, more exposure to countryside or children perhaps.
The first is mine, when its cold having cold cleaveage is hideous.
The second is K's, your child insisting on putting cars down your cleavage is equally as hideous, particularly if its cold, or if they try and retrieve them.
