Some reasons why I love my sister:
She doesn't own or wear any white clothing, because she will spill on it and she knows it.
She is hilarious and doesn't realize it.
She stumbles/falls more than anyone else I know and always laughs, because it's always ridiculous yet not unexpected.
I have many memories of things she has done that will make me laugh out loud, in public or alone, years after they happened.
She's one of the smartest people I know.
She has no idea how gorgeous she is.
She lets me pick on her when we're together because she knows I do the best M impressions, and I make fun of myself more.
She's taken more shit from me, being a snotty little sister, than anyone over the years and still manages to be my biggest fan. (Thanks, M.)
She is my biggest fan.
She drinks as much whiskey as some of the actual cowboys I've met.
She spends about 3 minutes ordering a martini (cheap gin, up, in a tumbler, extra olives) because the waitstaff can never seem to understand that what she wants is a regular dirty gin martini but in a cup rather than martini glass because she WILL spill it all over.
She has inspired strangers in restaurants to order what she's having just because they saw how she ate it. (Think When Harry Met Sally orgasm in restaurant scene but less perky and annoying.)
This is by no means a complete list.
