i can't recall exactly what the reason was as to why i wasn't ever invited or not allowed to attend. don't recall anyone ever telling me a specific reason , i also never once attempted to gain entry to a party uninvited. so i don't know what would of happened had i showed up to one.
also didn't have a part time job in high school so i wouldn't of even been invited to a staff holiday party when they still had those. only social event i can recall attending was a dance and holiday formal both of which were obviously held by the school and not at private residences.
recall that i was somewhat socially awkward back then and ate lunch alone at a pizza place downtown away from the school cause i liked the walk and break. i remember being told that guys there hated that i liked to look at there girlfriends and check them out. not sure if that is a possible reason as to why i was excluded or not. but i don't recall any girls saying they''d be uncomfortable with me being around them at such events
guess it all was a long time ago but a part of me is bitter that i didn't get to experience some of the normal things teens got to do at that age
