# Did you forget to double-check?

Lo! I heard you have gone to war.
Alluding to my utter demise.
Trees are what you used to fear,
blobs of nothing, nothing is best.
Do it no more than once, down these rickety stairs.
Take a notice, ignore the spaces in between.
No, doomed you are not, lest you count the punctuation.
(Count the space here, and ignore the first-born!)
Now, talk, flail, and stop right here.

Now that you've got what I've meant to say, double check.
I would warn you of anything, coming at your door.
Trust me, trust me! And say it once more.
So trust me, trust me! Did you forget to double-check?

Hints:

Do not take the first stanza literally. Very few words in it help you, but oh, how important they are!
The second stanza is really just emphasizing a portion of the first, and does describe a bit about the object.
I think I've said to much $\tiny\text{ But look at the tag. }$

• Can somebody do anything with the letters "lteebnntmeessedoutnle" ? (I can't and I'm going to bed now..) If you wonder: I've looked at the title of the riddle and the first 2 paragraphs one. Stop here. – BmyGuest Dec 17 '14 at 22:34
• @BmyGuest How on earth did you get those letters? – Conor O'Brien Dec 18 '14 at 21:23
• All letters which appear twice in any word. Double-checked :-) spontaneous idea, but obviously wrong... – BmyGuest Dec 18 '14 at 22:03
• @BmyGuest Oh, wow! That's really clever! Kudos, kudos! – Conor O'Brien Dec 18 '14 at 22:04

It is

A doorbell

Hopefully no further clarification is needed.

I was originally going to give up on this line of thought, but then I double checked and realized it was backwards. True story.

• @McMagister, you need to remove the "gi" from your username! – pacoverflow Dec 19 '14 at 16:34
• very clever, dear sir :) – zlobi.wan.kenobi Dec 19 '14 at 21:23
• Perfect, nice job! (Truth be told, I got inspired for this whilst falling down a staircase XD) – Conor O'Brien Dec 20 '14 at 2:44
• Also 'doorbell' sounds like 'double' as in double check :-) – Rand al'Thor Dec 20 '14 at 23:26
