WHT MEN DON'T WRITE TO AGONY AUNT'S

Ever wondered why you rarely see letters from men in agony aunt columns.... Dear Abby, I've never written to you before, but I really need your advice on what could be a crucial decision. I've suspected for some time now that my wife has been cheating on me. The usual signs... phone rings but if I answer, the caller hangs up. My wife has been going out with the girls a lot recently although when I ask their names she always says, "Just some friends from work, you don't know them." I always stay awake to look out for her taxi coming home, but she always walks down the drive. Although I can hear a car driving off, as if she has gotten out of the car round the corner. Why? Maybe she wasn't in a taxi? I once picked her cell phone up just to see what time it was and she went berserk and screamed that I should never touch her phone again and why was I checking up on her. Anyway, I have never approached the subject with my wife. I think deep down I just didn't want to know the truth, but last night she went out again and I decided to really check on her. I decided I was going to take some photographs of my wife coming home using my new camera and waited behind the garage to do this. When I fired the first shot the shutter jammed.

Is this something I can fix myself or should I take it back to the dealer?
