My real big sister was a psychotic bitch..to this day i still hate her, my junior year i was adopted by the person that i now consider to be my big, i call her big, we are really close, she is the one that i trace my family tree back to, etc..however..in my chapter there is no official process of doing so, she just adopted me..and thats how it was..coincidentally my 1st little ended up adopting my first grandlittle after her big resigned..and after i went alum i became close with a girl who was affiliating with my chapter and she asked me to adopt her..so i did..so i guess you can say i have the adopted family
but again..there really wasn't any official process, its just something we said okay you're my big. no paperwork or anything
