I may seem real yet I am not,
Once you're gone I'm often forgot.
Time here stretches and it shrinks,
It all depends on how you think.
I may be good, I may be bad,
I may be the same as one you've had.
What am I?
Some people prefer them with raisins
Some like them to contain chocolate chips
Whichever kind of these you like though
They don't last long once they've passed your lips
What are they?
I am a home of knowledge, both banal and profound.
In grand halls and small homes I can be found.
I am a home for things of many leaves,
but my many residents are not living trees.
What am I?
