Us girls have our own secret language but some boys are stupid enough to not understand the hints.
When we say we are "fine" or talk one word sentances we are pretty upset about something.
When we say "I'm just tired" when you ask us what's wrong, more than likely we are too afraid to tell the truth and/or something is bothering us.
If we say "I don't care" that usually means that we do care really much.
If you look inside a girls heart she has many things that bother her and tears waiting to come out. The teenagers are the ones that seem like they have something to cry about.
Boys, any girl that you get, you are very lucky to have (no, I'm not talking just the ones that want to get laid or w/e). She may take most everything you say to heart because she likes you alot and she feels lucky to have you. If you actually believe the "I don't care"'s , the one word sentances or the "I'm fine" phrases then you really need to straighten up and stand tall next to her. Hold her through the rough times and try your best at the realationship. Us girls love the attention and the love you give us.
