We don´t forget, we simply can´t remember.
Means everything is still hidden somewhere in the furthest corner of your mind, you simply have to search at the right place and you´ll find your memory.
Go to places you´ve visited together or search for old photographs and you´ll see that your memory will return.
Every memory returns one day, often at the moment you expect it least.
>>2 The past is in the past - true. Nevertheless, the past is what shaped our current self, we shouldn´t forget people we once held dear; at least not while we´re young. For every occurrence, every person we once met made us the person we are now.
