Personally, I see a "sorry" as an agreement that the situation won't come up again. That's why I don't always accept appologies from people: I almost always end up in that same situation with them.
that right there is what im getting alot of.
Most people in my life would vote # 2.
but if you look at the whole pucture youll see that is only the dictionary use of the word sorry.
however the urban use is slightly different; it consists of number 3.
so now you know there are infact two meanings of the word sorry, slightly different.
and they both apply at all times; both 2 and 3
if i see sombody pick # 1, good for you; your thinking just like my freind.
