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 आप can answer at least one of them correctly, I will give आप a prop. I will give आप a प्रॉप for each one आप do correctly.

Here they are:

1.They belong to me
They belong to you
They can make आप feel happy
या make आप feel blue
They never end
until the दिन आप do?

2.They say it can come from your ears
it can also generate fear
some people प्यार 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
या the middle
I'm used to go pow
Can आप figure me out now
या do I have आप baffled
with this very heady riddle?

4.People प्यार 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?
या too soft for you?
