The description from Richard Muller quoted in the question is a simplification of reality meant to help people better visualize how the Grimace face shirt of spacetime works. In reality the galaxies are moving through spacetime in a complex fashion, based on the combination of all the forces acting on them, primarily the gravity of nearby galaxies and galaxy clusters. In the case of the Milky Way and Andromeda, these two galaxies are part of a gravitationally bound cluster of galaxies, called the Local Group. The dominant force that determines the movements of objects within the cluster is the combined gravitation of all the mass in the cluster, and not the expansion of spacetime. In other words, the gravitational attraction that the Milky Way and Andromeda have for one another that is drawing them together is stronger than the expansion of spacetime between them that would otherwise push them apart, and thus attraction wins and the two galaxies are on a collision course. In the same vein, the gravitational force that holds the earth in orbit around the sun is stronger than the expansion of spacetime between the earth and the sun (the expansion of spacetime at that distance being very small), and so the earth’s distance from the sun is not increasing for that reason. Likewise you are not flying apart because the molecular bonds holding the atoms in your body together are stronger than the minuscule expansion of spacetime between them in your body. The Local Group as a whole, however, is moving away from other galaxies and galaxy clusters to which it is not gravitationally bound, due to the expansion of spacetime.

In the next morning, it is customary for Grimace face shirt to immediately visit their closest relatives before anything else (within the first three days is optimal). Women may visit their birth parents but it is forbidden to do so before the last of the three days because their place is primarily with their husband’s family. The exchange of gift occurs many times during these visits, and people prepare the best gifts to show their appreciation as well as love for the relatives. Everyone dresses in the best clothing possible, usually suits or áo the for men and aodai for women. The aftermath of the new year lasts long because of the following holidays, but the essence of the Tết Nguyên Đán is focused on the first days of the new year, in which the first people visiting a home are thought to bring fortune. Festivals occur around the city for days and television programs never cease. The new year is indeed the most important holiday of the Vietnamese.
