There are plenty of reasons the city can tire you out, as well as the general gatherings at the entrance and the doorbell ringing at all hours. Everything that goes along with choosing to live in an apartment. But still, in the ranking of the three most important things, we can sort out the most common.
You have a dog. Not just a little fluff ball that you carry in a bag at the mall and that sleeps on your lap at the hair salon, but a very real dog. It needs space, a house in the yard, easy access to grass to dig in, and above all the freedom to gnaw on its bones without getting remarks about spreading meat around the living room. In fact, if a family lives in a house, they are sure to have happy children for having a pet and a pet happy with the fact that the yard is a door away.
You have children. Children are not angels with blond curls, Little Prince clones, or Sleeping Beauty Princess Belles. They are those creatures that nature has endowed with inexhaustible energy and they are the more excited the more noise they make. They spill the box of constructor parts, build tracks and throw cars on them. The list could go on forever. The kids make so much noise that the downstairs neighbor calls the police, the cops hold you responsible for your children's poor control, and you just want those years to fly by faster. In all the hubbub of toys and games, you completely forget that you are victims too.
The upstairs neighbor loves to poke holes. Not ordinary holes in the furniture or for a cornice, but whole long, wide, serious grooves in the slab in which he arranges his cables. Lord of the cables. The years pass, the need for holes does not. Neighbor knows the national holidays better than anyone, and apparently plans to delight you with the sound of his drill on each one. Your incomprehension of his greeting is entirely your problem.
Or it isn't. In an instant it just comes too much for you. That's the moment you decide life is too short to live it in an apartment and start picking out a house.
