This is how I feel. Assuming no laundry during travel, I always go with the "# of underwear = number of days + 2" rule, because I have some engrained fear that I'll shit myself, not just once... but twice... and run out of underwear.

I love that this is the joke that we all worry about shitting ourselves but I legitimately bring extra because I worry about things like sitting on a wet chair, or being caught in the rain. When you get wet to your core you never feel dry again until you have fresh undies

Also I haven’t seen this brought up yet but if you’re a person with a uterus it’s not uncalled for to change your underwear more than once a day. Sometimes that brat just has to make a mess and ruin your fresh pair just because she feels like it. (I can call her bad names because I have one and she is in fact very rude to me and I don’t appreciate what she has done to my undies…) and this goes for any time of the month. Sometimes we just don’t know what to expect.
