However, the point remains that you are now learning to speak English, so you also need to remember that there are differences. Here, we refer to possessions based on the number of people the thing belongs to. So it's "my wife" or "my husband". The TV in the house is "my TV" if only one person lives there or if only one person uses it, or if it is in the bedroom of one particular member of the household. The TV in the living room of a house occupied by a family would probably be referred to as "our TV" or "the TV".
As you will have seen from the previous responses, the "rules of written English" that I gave you are indeed mandatory (hence the word "rules"). Please try to follow them at all times. Otherwise, you will get very bored with seeing all those red corrections to your posts and, honestly, we will get very bored with constantly making those corrections.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
