<human>: A little backstory, last winter I went to New York for the first time (I live in south america) with 2 friends. One day we decided to go to The Cloisters. Once there, we realized we just pretty much wasted a day to see some tapestry's which 2 of us didn't care about, and this is here we turn stupid. For some stupid reason I decided that shoplifting a calendar from the gift shop would be a good way to spice things up. We left the premises without anyone noticing us and everything went smoothly, we had a good laugh and that was it. Later another friend of mine who lived in the US for a year told us the story of another south american dude that was an exchange student who was sent back home because of shoplifting, and according to what he tells us, he's not allowed back in the US.   
After hearing this we all felt really stupid and lucky that we didn't got caught. I've felt a little paranoid about this since then, but decided it wasn't worth paying attention to.   
The problem now arises since it seems I might have a chance to go back for the holidays. Most people tell me I watched a little too much CSI, but I think it's possible they may have gotten my fingerprints from the place or maybe they got me on the surveillance video or something of that nature, and now I'm on some sort of blacklist and wont be allowed to enter the country.
This is really keeping me up at nights, since I'd love to go back, and I know I should have though about this before doing it, but now it's done and there's nothing I can do.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Shoplifted a calendar from a museum, didn't got caught. Now I'm afraid they won't let me inside the country again.
