my sister was convinced, when we were little, that we had 4 brothers. in fact we only had one. she said that jake and john were her triplets and that freddy was a year older and adopted (she also said that he was jewish for some unknown reason) and then our actual brother brian (who was over 9 years older than me). she told me that my mother sent my 3 brothers away because she didnt like them, which to my 4 year old self made sense because my real brother was honestly my half brother and lived with his mom. years later i found out the truth- i was quite relieved i kept on worrying that my mom was gonna send me away- but we still laugh whenever it comes up. and occasionally we try to fool our friends.
