I made a couple of worksheets to go with this lesson. The "Do You Mind" wksht can be used by telling students to go around and ask their peers the questions using the dialogue and the given vocab. It's pretty self-explanatory and easy to understand. I have used a wkshet designed like this before and I didn't have too many problems. Possible problem: students will copy each other instead of talking, so watch for that.
The "I should have done it" wksht was made for group work, but I suppose you could give it to all students and have them go around the room and ask each other to share their experiences. I'm doing group work and making 6 groups of 6 students, and they will have to pick the best experience and share it with the class. I've done used this before and they really enjoy embarrassing each other

One time, a past student shared how he shit his pants at Lotte World. I was surprised he admitted that, but everyone was laughing and no one was mean. I'm going to give one sheet to every student to encourage all students to write, but it also works if you give one sheet per group. You can have them pick one student to write, but then the others have to do all the talking (this is good if you have a higher level student in a group of lower level students), or have each person pass the paper around and take turns writing and speaking. Each method can be used differently to control class management, that's why I offer different methods. I also included some Korean instructions on the second wkshet to cut down on potential co-teacher's talk time.
