Do you have a brother or sister? Are you an only child?
One of the main disadvantages of having a brother or sister is that your childhood is very lonely as you don’t have anyone to play with. Moreover, your parents pay you more attention and you might be “ limited “ by them in some ways. In adition to this you might be too self-confident.
However, there are also advantages of being an only child. First you have your own room and you don’t have to share anything with someone else. Besides you have more money – for example bigger pocket money and also it’s easier to convince your parents to buy you something or to do something you want to. Furthemore, you have everything new – you don’t get things, especially clothes, from your older sisters or brothers.
