This topic is about short riddles, because not everyone likes to do the larger logical puzzles. If you do like those, then click here.
If you've guessed the riddle, you can immediately post another one yourself. Let's keep it going. 
I will start with this riddle:
What is easy to get into, but hard to get out of?
The first of this threesome is the last to arrive, the other two are twins, merely 15. Once brought together they imprison many, and display their captives for the entertainment of the money holders.

@DarkWolf My husband thinks the answer is zoo.
@Lifer That is a great answer.
@Bearlysane- thanks! I wonder what the correct answer is. :)
@Lifer
Zoo is correct 
@DarkWolf 💖 glad to see you Darkwolf!
I might come through your window,
And I'm often at the bar.
Sometimes I'm used to send your kids
To die in lands afar.

very nice@DarkWolf
Is the answer FLY
I will give it a try:
This belongs to you, but everyone else uses it. What is it?
@Bearlysane In addition to @lazyKatz idea, I say 'name'.
Address
Name sounds much more likely, good answer.
@lazyKatz Both make sense :)
@cloudySummer
Well done, I often try on here in the vain hope that I improve with my guesses. So far I'm not having much luck.
@lazyKatz Lucky or not, I'm glad you're here :)
Silky and soft we are, perfuming your lives.
Take us to your love,
but beware of our knives.

I am eating with a B
I am beating with a C
You will never show me to your spouse
And I never leave my house
What am I?

Enter through one, exit through three. Once you succeed I am on thee. What am I?
