I recently ordered a bunch of makeup online during a sale, and as part of a promotion, they included three small free samples. I was genuinely excited because I’ve been treating myself sparingly lately and didn’t want to spend too much, so getting a few little extras felt like a fun bonus. I carefully opened my package when it arrived, admiring the items, and set the free samples aside to try later. Later that day, my friend came over. She noticed the samples immediately and reached for one, and said, Oh wow, can I have this? I was caught off guard and told her, Uh, actually, I wanted to give these to my little sister. She got upset already and said, It’s just a freebie, what’s the big deal? I tried to explain that even though the samples were free, i have already told my little sister that i would give it to her, and my little sister was really looking forward to using them. At first, I thought she’d take it lightly, but then she's not fine on what i have said to her, I tried to brush it off, but her tone made me feel kind of judged, and she muttered something under her breath about me but i coudn't tell what she said, but i know its not a good word. After she left, I kept thinking about the what happened and felt a bit awkward. I’ve shared makeup with friends before, but this time felt different because this is for my little sister and she was really looking forward to trying these specific items. I started questioning myself if i should just give it to her? I don’t want to start a fight between us, but I also want to respect my own boundaries and. I don’t think I’m wrong for not giving my friend my make up. At the same time I want to know if what I did was the right or wrong AITA for wanting to keep my free samples to myself?
