is it good to have a sibling or not.

Is it good to have a sibling or not. In someways having an older or younger brothere or sister is good and bad. But don't think about the bad times about you brother or sister think about the good times you've had with them. Now i am just an only child but i see how my friends are to their brothers or sisters aor brother or sister. my cousins especially. I see that they always say they hate them. wether you hate them or not. I know you will always look out for you brother or sister and love them even though you say you hate them. A brother/sister is there for your love and and companionship i don't know what it is like to have one but what i do know is that how you guys should treat them. Now when you read this I would like you guys to comment back and plaese tell me what it is like to have one.
