... that you care about, that you remember their birthday and prepare them a gift. That one person you thought you could call friend.
But then... when your birthday comes, that person doesn't even wish you.
Yea.. that one person you thought was your friend, actually doesn't care about you.
In the end, they disappoint you. In the end, they are not really your friend.
At least you know, before you waste more of your time of that person.
