why do we forget things?!

Because you only put them in short term storage "memory". If you can manage to put something into long term storage you'll never forget it, however your ability to access it at will is another thing all together.
Human minds keep modern, up to date, important information. There are two memory composites in the mind, long term and short term. While yes, sometimes we remember old, useless information, The mind is often times more likely to put old information away in a metaphorical file cabinet. When such are topics are brought up, the mind is immediately able to remember such.
encoding failure or retrieval failure.
encoding failure: unsuccessful storing of info into ones memory.
retrieval failure: lack of retrieval cues to retrieve info from one's memory
because it is not the focus of our attention,, if you notice there are quite a few things that require very little attention, for example on friday what pair of shoes did you wear, this is usually easy to remember, you may only have one pair of work shoes, or you can remember picking them out to match an outfit, but do you remember which one you put on first..
