Boobs aren't bad

Ok let me tell you this short story about how just now I got yelled by some women today...I'm 15 and I wear 34DD size bra and I kinda have bad Asthma btw... Ok so today it's Hot as the devil himself and personally I don't like bras out of my life I wear bras like 1% of my life I hate the way it feels n it hurts sometimes...anyways today I decided to wear one of my cute halter tops so I can keep cool but I don't wear a bra when I wear that type of shirts normally I wear pasties to cover the nip nip but I didn't have any...anyway I went out of the house with my mom (she's ok with the fact I hate bras) n went to the store this woman came up to me after my mom left and told me I shouldn't walk around in public with my titties all out. I was so confused everything was covers except a little side boob so I asked Wym n she said I can see ur nipples. I said so their not hurting anyone so she walked over to my mom and told her I'm not wearing a bra. My mom told her why I don't wear them. Tbh they hurt like really bad and I can't really breath with one on it adds so much pressure on my chest n rips that I had to take super deep breathes. I tried everything nothing helps so I just don't wear one... The woman told me and my mom she's sorry then left...
