Home,
sweet home. It does not matter what your home is like - a countrymansion, a
more modest detached or semi-detached house, a flat in a block
of flats or even a room in a communal flat. Anyway, it is the place
where you once move in and start to furnish and decorate it to your own taste. It
becomes your second “ego”.
Your
second “ego” is very big and disquieting if you have a house. There is
enough space for everything: a hall, a kitchen with an adjacent dining-room, a
living-room or a lounge, a couple of bedrooms and closets (storerooms), a
toilet and a bathroom. You can walk slowly around the house thinking what else
you can do to renovate it. In the hall you cast a glance at the coat
rack and a chest of drawers for shoes. Probably, nothing needs to be changed
here.
You
come to the kitchen: kitchen furniture, kitchen utensils, a fridge with a
freezer, a sink, a dishwasher or at least a dish drainer, an electric or gas
cooker with an oven. Maybe, it needs a cooker hood?
The dining-room is
lovely. A big dining table with chairs in the centre, a cupboard with tea sets
and dinner sets. There is enough place to keep all cutlery and crockery in. You
know pretty well where things go.
The
spacious living-room is the heart of the house. It is the place where
you can have a chance to see the rest of your family. They come in the evening
to sit around the coffee table in soft armchairs and on the sofa. You look at
the wall units, stuffed with china, crystal and books. Some place is left for a
stereo system and a TV set. A fireplace and houseplants make the living-room
really cosy.
Your bedroom is
your private area though most bedrooms are alike: a single or a double bed, a
wardrobe, one or two bedside tables and a dressing table.
You
look inside the bathroom: a wash-basin, hot and cold taps and a bath. There
is nothing to see in the toilet except a flush-toilet.
You
are quite satisfied with what you have seen, but still doubt disturbs you: ‘Is
there anything to change?’ Yes! The walls of the rooms should be papered, and
in the bathroom and toilet - tiled! Instead of linoleum there should be parquet
floors. Instead of patterned curtains it is better to put darker plain ones, so
that they might not show the dirt. You do it all. but doubt does not leave you.
Then you start moving the furniture around in the bedroom, because the dressing
table blocks out the light. You are ready to give a sigh of relief, but…
suddenly find out that the lounge is too crammed up with furniture.
Those
who live in one-room or two-room flats may feel pity for those who
live in houses. They do not have such problems. At the same time they have a
lot of privileges: central heating, running water, a refuse-chute and… nice
neighbours who like to play music at midnight. Owners of small flats are happy
to have small problems and they love their homes no less than those who live in
three-storey palaces. Home, sweet home.-
