The Christmas fever has already arrived. So yesterday I saw the following weird conversation in a chat room:

-${}$ You know, I figured out what to buy ou for Christmas.
- What?
- I'll tell you on Christmas Ive.
- But I can't wait till then!
- You are smart! I am sure you will figure it aut.
- I will kill you!
- Stop being such a drama queen. Or should a say drama quing? See what I did? See?
- Oh, come on. That's not even remotely funny.
- Shall we go to the bub instead?
- The what?
- The pub. Sorry, slip of the fimgers.
- Are you drunk?
- Nope. I just drank some jin.
- You are drunk.

I am now wondering what the gift is? Can you help me with that?

Let's look at which letters have been changed:

• You know, I figured out what to buy [] ou for Christmas.
• I'll tell you on Christmas Ive.
• You are smart! I am sure you will figure it aut.
• Stop being such a drama queen. Or should a say drama quing? See what I did? See?
• Shall we go to the bub instead?
• The pub. Sorry, slip of the fimgers.
• Nope. I just drank some jin.

This should be:

• You know, I figured out what to buy you for Christmas.
• I'll tell you on Christmas Eve.
• You are smart! I am sure you will figure it out.
• Stop being such a drama queen. Or should I say drama king? See what I did? See?
• Shall we go to the pub instead?
• The pub. Sorry, slip of the fingers.
• Nope. I just drank some gin.

The new letters we get are:

YEOIKPNG, which anagram to ... KEYING OP? EGO PINKY?

Or rather (thanks @LukasRotter!) the following:

Thanks to @Techidiot for spotting

some of the hidden letters in this image. I bleached the background so as to spot them more easily:

And we have the letters

SSPPLEIR, which anagrams to SLIPPERS,
