We practice earthling proper egoism: we ignore cues that would not be properly "egoistic" and "gravitational":

Mind practice for the Aspect and the time frame:
2. The skylark found nothing to outbid the bit of cosmos with a squid.
8. The spotted redshank bachelorette bewailed, and reset her buret for the bouncing bet. ■→More
Madame Règle is not a systematic person at all. The only regularity about her would be a small book she always carries fastened to her bag with a scarf, or actually a variety of scarves, of many colors and textures. The book is not the same book every day, and the choice of the scarf sure depends on some totally unpredictable factor, just as the exact time for lunch, for which you might want to assume the broad time frame of about sixty minutes to commence or not to happen altogether.
