<human>: Fyi, i hate wearing glasses. All day everyday. But i learned today why i should.

First let me give you the beginning before we get to the point. 
I moved to another zipcode almost a year now and because my daughter of 7 still wanted to end her schoolyear on her ol school before going to a new school in the neigbourhood. I said yess. Here is where it starts. Because i do everything with a bicycle, i would bring her every morning and pick her up every afternoon. But the fastest way to get to her school i have discovered short cuts between houses. There is this neigbourhood where my short cut runs through. And i dont know why, but they put up posters up on de door to their garage. And i've been seeing this particular poster hanging of 2pac holding a white baby. For months i've been trying to figure this out. Like why is 2pac holding a white baby. Everytime i passes the poster i reminisced about the good old days and trying to find out what the purpose was of the white baby in his hand. Untill today. Today i had my glasses on. When i picked my daughter up from school, i took as always the same shortcut through this neigbourhood. I wish i wouldn't. When i passed this particular house with 2pac holding a white baby, as always i looked at the poster like it was a common friend but this time the poster felt like a stranger. Instead of 2pac, i saw a big, black, bald, big ass muscles man holding a white baby. So all this time i thought it was 2pac. And telling my daughter what a good rapper he was. She'll forever think 2pac is a big, black, bald, big ass muscles man who likes to hold white babies.

Can you give me the gist of the text in a nutshell?
