sister is self-centered

my little sister is so self-centered! my god she is so self-absorbed! So full of herself. my older half-brother [finally] came to visit the other day. my little sister straight up said "I'm your favorite little sister". WTH? When she was younger, she couldn't stand him! Hypocrite much? Then we started reminiscing about times we got free food (due to wrong orders) and she replied "I get free stuff cuz I'm cute". Geez what a giant-ass ego on that one. XP
