Might be more personal than OP is asking, but during my senior year of high school I decided to live with my dad. And he had his girlfiend at the time (who was pregnant with my baby brother) move in with us. I wasn't fully aware of it at the time, but there was a powerplay/resentment thing going on with her when it came to me. She was barely ten years older than me (my dad was like 36 or 37 at the time, I was eighteen to give you an idea) and for some reason she just did not like me.
Come christmas time all of her family along with two of my other brothers from my dad's first marriage come to the house to celebrate. Dad decides everyone will stay up until midnight to open presents. I was excited since I saw quite a few big ones under the tree. I didn't really want anything, but I thought at least one of the semi-big ones were for me or I'd get some new socks or a jacket. (I really love wacky looking socks. I ask for them every year.)
Well, it comes time to open the presents. Everyone is handing them out, of course my brothers get a lot of nice things. New jacket, socks, clothes, toys, etc. Even the adults (excluding me) have gotten each other a few nice, inexpensive items for each other.
During this entire time I'm waiting. And waiting. And waiting...until finally someone hands me a bag. Inside is a blue long sleeved shirt. Not even wrapped or has any tissue paper to hide the fact there was just a shirt in there. Just a shirt that had been rolled up and thrown in there. I was really confused and looked around, but acted like I liked the shirt. (I did, I wore it a few times because it was winter.)
But the fact I just got this shirt in a bag while my brothers were getting christmas cards, toys, clothes, etc. Hit me really hard in the middle of everything. My dad and his girlfriend hadn't even gotten me a christmas card. It was the girlfirend's cousin who thought to give me the shirt in the first place, but compared to the nicely wrapped presents they'd brought I really felt like an after thought.
Oh, the kicker? A few days later I got lectured four times for not sending that cousin a thank you note for the shirt. Even though I had thanked them profusely when I 'opened' my present and told them I thought it would be perfect to wear to school.
