How did Jerry spend his weekend?

M: Hey, Paula. Did you have a good weekend?
W: Yeah ... I checked out that new 3D movie. It’s amazing what they can do with technologies these days! How about you, Jerry?
M: I went mountain biking with a couple of friends. We worked up a good sweat and had a good time.

M: Look at the text message. Do you see that she has written the letters LOL at the end?
W: Yeah, exactly. What does it mean? Is it an English word?
M: It’s a good example of English " text speak" , that is, language people use when texting, writing emails or talking over the internet. LOL stands for "laughing out loud".
