Hi, I'm Phil from BBC Learning English.
Today I'm going to tell you how to use 'too' and 'very'.
They are both intensifiers – but they don't mean the same thing.
We use 'very' to make an adjective, or an adverb stronger.
So we can say, "The building is very old." That could be a good thing - it's beautiful.
Or it could be a bad thing - it's falling down.
Or it might not matter.
If we use 'too' (with two Os), then it means it's a problem.
Could say, "It's too easy." It means 'it's a waste of time'.
It's a problem!
