When you hear or read though at the end of a sentence, it means however. It indicates that there's a contradiction or condition relating to what has already been said. Here are a few examples:
You: Did your mom like the restaurant?
Your friend: Well, I'm not sure. She didn't seem to like the menu, and she had a hard time deciding what to order.
You: Oh. That's too bad.
Your friend: She finished everything, though!

Dear Bob,
Thanks for sending the presentation. I think it looks good in general, and I like the images you've added. We shouldn't be overconfident, though. What would you think about getting Janice's opinion before we meet with the client?

Your boyfriend: It's going to rain.
You: Yeah, I know.
Your boyfriend: I still want to go the park, though. What about you?

P.S. A warm thank you to Pal, who suggested a post about this!
