I like cheese!

now that I have your attention (doing it in a way that was completely stupid) I've got a couple riddles here. If あなた can answer at least one of them correctly, I will give あなた a prop. I will give あなた a リスペクト for each one あなた do correctly.

Here they are:

1.They belong to me
They belong to you
They can make あなた feel happy
または make あなた feel blue
They never end
until the 日 あなた do?

2.They say it can come from your ears
it can also generate fear
some people 愛 to do it
indirectly some chew it
it's not welcome in a house
it's quiet as a mouse
What, pray tell, can it be?

3.I keep stuff in
I'm usually on top
I can sit to the right
to the left
または the middle
I'm used to go pow
Can あなた figure me out now
または do I have あなた baffled
with this very heady riddle?

4.People 愛 to get good ones
but the bad ones do come
you're guaranteed to get some
so take them and run
they will get things done

5.It flattens things,
and without it,
it flattens you
It's in food
It's in buildings
It's in bridges too
Is this too hard?
または too soft for you?
