I'm the oldest, with one brother 14 months younger than me. My youngest brother (there are just the 3 of us) is 7 years younger than me. I have 2 step-sisters who are a few years younger than my baby brother. I wish I could say I was close to my brothers, but we've never shared the same interests. We love each other and would have each others' backs in a second, but we never really hung out much.
Biological: I'm 6 years younger than my older sister, 1 and a half years younger than my older brother, 4 years older than my younger sister and 8 years older than my younger brother
Step sibings: I'm 9 years younger than my older stepsister, 5 years older than my younger stepbrother and 8 years older than my youngest stepbrother.
Everyone I talk to is usually pretty shook when I tell them my sibling is 9 years younger than me...so I wouldn't want to know how some of you guys feel when you tell them your age gap xD
