The words "i love you"

ok ok so this has been a question i always have had lol when you say to some one "i love you" what does it mean .... i mean i know the difference between " i love you " and "I'm IN love with you " BUT i HATE it when some one say "love you" or "love ya" when its the person you really love cause usually i will say that when in irritated or upset about something insted of saying "i love you " i will say "love you" or "love ya" ..... cause the words "i love you" are thrown around and said to every guy / girl Friend you love. So how is is suppose to be special between you two when it is said to everyone of your friends ???? but then again il say "i love ya" to all my friends and they know i love then LIKE a friend Right ??

i just dont get it

some times i dont even understand my own brian
