Is AUTHOR wrong in the post ? POST : My sister and I went to an arcade where all your tickets for prizes and gaming credits are loaded onto a card. The problem was that each new card that is created has a $5 activation fee and so my sister suggested that we share a card so we only have to pay one activation fee. That made sense since we were going to stick around each other anyways, so we got one card and loaded it with gaming credits and started to play games in the arcade. Most of the games my sister played were games that did not give tickets such as Dance Dance Revolution while I solely played games that gave tickets. Once all our gaming credits were gone we had 2000 tickets to spend on prizes. My sister and I couldn’t find a prize we both wanted so I said since she paid for half of the card and I paid for the other half, she can spend 1000 tickets while I spend the other 1000. I decided to get a rock salt lamp for 950 tickets but my sister wanted to spend 1,500 tickets on a giant llama plushie. She wanted to use some of my tickets and argued she wanted the llama plushie a lot more than I wanted the rock salt lamp, which is probably true since she made a big deal about how much she loved the llama while I just got the rock salt lamp cause I thought it was cool. That being said, that doesn’t mean I didn’t want the rock salt lamp. I told her no we’re not getting the llama and that we were going to split the tickets in half evenly. Plus, she could get a normal sized llama plushie for 700 tickets and still have some leftover for something else. She didn’t like that I said no so she then brought an employee over and asked them whether or not we should get her the giant llama (thank goodness the employee didn’t view it as a nuisance, he was very kind and just laughing at the whole situation). The employee asked for my side of the problem and I told him my sister and I should split the tickets in half evenly so it’s fair but my sister told the employee to think of the emotional aspect of it: a giant llama is going to make her a lot happier than rock salt lamp is going to make me. The employee then said he agreed with me and so I started walking to the cashier to redeem my prizes. My sister kept trying to block me from getting to the cashier and then said “You’d get me the giant llama if you loved me,” so I said “I guess I don’t love you then” ¯\_(ツ)_/¯ since I definitely was not getting her the giant llama. I budged past her and redeemed my prize and gave her the card to spend the rest of the tickets on anything else she wanted. But she just stomped away and said “I don’t want anything.” Later on she told my mom about what happened and how I didn’t let her get the giant llama plushie and my mom got mad at me and said as the older sibling I should’ve gotten it for my little sister. She gave a whole speech about how she’s my little sister and I should love her and do stuff for her to make her happy and that I am being selfish for getting the rock salt lamp. 

AITA for not getting a giant llama plushie for my little sister?
