What should i do? About hanging out ?

I went to the store w/ my grandma and mom today and just got back like 20 minutes ago. And on the phone my bf called on a pay phone like 5 times. Me and him were going to the mall today but i told him to call me b4 he left . Hes been waitin for me since like 10 hes leaving at 5. Hes all alone at the mall waiting. My mom said shed let me hang out with my friends today if i went to the store with her and i did and wen we got home i told her if i can hang out at the mall and she said noo why the **** are you so worried about ur friends and not anyhing else. Then she went back to thr store w/ my grandma. And i really wanna hang out with my bf so he doesnt get madd.
