I tend to think it happens all the time and in every relationship. It's everywhere.

There are major transference reactions and smaller, less significant ones, I think. Something happens and it reminds you of a feeling you've had in the past and so you react to the feeling now in the same way you did in the past. I don't think it means you think your therapist is your mother or anything, but that you may react with the therapist in a similar manner that you did with your mother. So basically you can see the things you tend to do within relationships and why. You can see what effects the relationship negatively and then try to change your pattern of response.

Just this week, my H got upset with a customer because my H printed out the wrong lottery tickets for him. I later explained to him that his reaction was an overreaction to the feeling of having done something wrong. Probably from something in his past. That has to do with him and not the customer. This stuff happens all the time. I really believe that.
