Turn the music down, so you can concentrate.
Tell the girls to lighten up. So you can concentrate.
Take regular breaks and have a drink and something to eat, so you can concentrate.
Make sure you concentrate on what you are doing. You may have killed yourself and your passengers and maybe someone coming the other way as well.
Start to take your driving seriously because if you don't you could be dead.
Sorry TC don't want to sound nasty but too many people are dead because they don't pay enough attention to what they are doing. They joke with friends, listen to loud music, dance around in their seats etc etc.
Driving is serious and it needs to be taken seriously.
Glad you and your friends are OK.
