Today's Phrase
If you make a beeline for someone or something it means you go straight to them.
Examples:
As soon as the concert is over, we should make a beeline for the car, because I don't want to get stuck in traffic.
The tired and thirsty travellers made a beeline for the bar.
Take note
If you have a bee in your bonnet it doesn't literally mean that you have a bee in your hat. It means that you are obsessed by a thought or something that you want to do. You can't get it out of your mind.
Example:
John really has a bee in his bonnet about the environment. He's always talking about it.
Interesting fact
Bees perform an essential role by moving pollen and nectar from one flower to another. They pollinate the flowers and trees, which means fruits and vegetables can be created and can grow.
