people used to make fun of my "rituals" growing up. and it wasnt until this past year i even realized this. and people -even my "peers" would ask me why i did certain things. for instance i alway said "bye otis, i love you otis, see you later otis" before leaving out the front door(otis was our dog, and i was about 8 when i remember this started) then as it grew i would get interrupted by my parents who also would stop me and question why i did it. and with that, it grew even more to where i would say it, and then go for the door and i wasnt okay to go without rambling off one of the three things i always said. to the point where i couldnt leave because i was stuck in that ritual... then in teen years, it slowly added some pets along the way.. it was a mouth full, "bye otis, skye, clover, and hollie! i love you otis, skye, clover, and hollie! see you later otis, skye, clover, and hollie!" ...
now i still do stuff but theres no one there usually to point out, or to rush me, or to interupt me, or anything now. and i recently realized i do the same thing with my best friend. at the end of our IMing when we goto bed, it has about 4-5 lines of the same thing and we repeat it back to each other. and if it isnt done then ... i cant really explain what it is that i feel, but its not a pleasant feeling.

its only too late when you accept that it wont change.
but it's not an option to pursue Sara any further.
maybe another individual on the spectrum could be a good friend?
