Dear Jessie, In your last email you asked about my friends. Well, I (have) lots of friends, and I (know) some of them since I started school. My best friend is Deirdre. We always (send) text messages to one another and we (try) to meet up as much as we can. I (start) a new hobby recently, rock climbing. Deirdre is much better than me so she (help) me. This weekend, my friends and I (go) out clubbing. One of them (celebrate) her birthday on Saturday. We're really excited as we (look) forward to it all week! I (take) my new digital camera with me so I'll send you some photos of the night.
