I think this is cartoon me when i am by myself and something hilarious runs through what passes for my mind these days. This happens a lot.
Gotta modulate the volume of laughter for my neighbors’ sake. And, ya know, laughing aloud alone does give unfunny folks the creeps, perhaps.
Shake it out of the shoulders, close the throat to get less-resonant and wheeze a bit.
Feels nearly as good as belly laughing.
