A little offended... anyone else?

Monica • Baby boy due June 2017 ❤️
I am not one who gets offended easily and I ALWAYS swore to myself that if anyone ever commented on my pregnant belly when the time came, that it wouldn't bother me like other women. I'm 20 weeks & went to Sally's today and the cashier asked when I was due. It caught me off guard and I looked at her for a few seconds and I just said "June" and kinda felt a little offended that she just assumed I was pregnant and not fat 😂 now I feel rude. I kept the conversation going so I could redeem myself with a nicer tone. Anyone else felt a little offended by those questions though? Or am I just a brat today?
