Try to elaborate on it, like why it was significant for you, mine is 1999. In the summer of 1999 i got to hold a girl i liked for the first time, also it was the best year because other significant things happened to me, and i feel like my life was great up to that point and then it started to go down hill after the end of 2000, and only recently started to get better. Everything referring to that year, such as music and films take me back, sometimes i stopped myself from listening or watching too much, cause i fear after a while the memories they carry will be washed out. There are also a few perfumes that take me right back, those were truly the happiest times of my life. However I feel like I'll never experience happiness with that intensity ever again.
