So we're walking along the street

After a fund raising dinner Regina, her mom and I are walking to the car and Regina pulls over to puke in the curb. I, rather by habit at this point, pull her hair back and patiently wait until we can keep walking. When I looked over at her mom and saw her eyes wide and she was asking if she was OK, I realized that I guess it has gotten normal for me to be around some one who can catch a whiff of, well, anything and throw up. I used to think that all the hormonal weirdness was like being around insane person. So what does it mean about me that it now seems normal?
