Spanish Speakers - differences between Preterite and Imperfect - visual ideas are needed!!?

Well, "preterit" kinda sounds like "precise," like it's an event that occurred at a precise time. Imperfect is kind of like someone keeping track of time (they're not perfect at it, so it's a general, unknown length of time). So you could have two different watches or something, one with a precise time, like 7:30 a.m. and one with a general time, like during the summer.
