Everyone experiences transference. Any time you are reminded of someone else, that's transference. With T's (and teachers) and older adults especially, we don't know much about them so our crushes on them cannot be about "them" the feelings are all coming from us and what we would like. Getting full blown angry at someone for a minor reason, that's transference; I got road rage because a coworker had cancer and I was feeling helpless so "took it out" on someone else. I called the manager of my grocery store and yelled at him because I forgot the bag with a couple cans of inexpensive cat food in it; what was he supposed to do about it? I got a clue and looked for the transference because it wasn't "like" me to do that. The term "kick the dog" has to do with transference; the guy gets yelled at by his boss and can't reply for fear he'll get fired, comes home and yells at his wife that dinner's 5 minutes late and she yells at the kid for dropping his ice cream and he kicks the dog for getting the ice cream instead of him. We cannot make our parents love and care for us the way we want to be loved and cared for and, when we are very young, can't even articulate what we want (so are less likely to get it, especially if we have non-emotionally-astute parents; you are hungry and your mother changes your wet diaper, that sort of thing) or understand why we get one thing and not the other.
