Learn the English Phrases TO GET THE WRONG IDEA and ROUGH IDEA

In this English lesson
I wanted to help you learn the English phrase,
"To get the wrong idea."
When you get the wrong idea about someone,
it means that you've seen them do something
and so you think they do that all the time.
You kind of judge them.
Here's a good example.
Let's say I'm driving down the road and it's really warm
so I roll my window down.
Actually, you just push a button now, don't you?
Anyways, I have the window down
and maybe there's some garbage in my van
and the wind inside the van makes it blow around
and it flies out the window.
My neighbor might see me and they might get the wrong idea.
They may think that I'm someone that doesn't care
about the environment and someone who just throws things
out their window all the time.
So when you get the wrong idea about someone,
you make a judgment about them,
you think they are a certain way
because of an action they've seen you do.
Certainly I do not throw garbage
out the window when I drive,
but if some blew out while I was driving accidentally,
someone might get the wrong idea about me.
The second phrase I wanted to teach you today is the phrase,
"A rough idea."
So a rough idea is like an estimate or a guess
about how much or how long something will take
or how far something is.
If someone said to me,
"Bob, do you have a rough idea
how long it takes you to get to work?"
I would say, "It takes about 10 or 15 minutes."
I don't know exactly how long it takes,
but I have of a rough idea how long it takes.
So a rough idea is just an estimate.
