Walked into the Muir Trail Hut with a decent looking middle aged weekend hiker type female fidgeting with her bra strap. I caught her by surprise. Since we were both alone it was awkward for her momentarily. Kinda awkward for me too. She didn't want to readily admit to her "gear" issue but it was obvious to me what her problem was. My first thought was what the heck are you doing hiking in a strapped bra with clasps anyway? I thought that! I didn't say it out loud. She eventually lightened up enough to tell me she had a clothing issue. I offered her one of the small safety pins I always have attached to the outside of my pack. I didn't have to say anything. I just went outside for a few mins. Came back in and we both shared a few smiles and laughs. She blushed slightly as she thanked me. I do what I can for you ladies.
Story doesn't end there. A few yrs earlier on a Oct JMT thru-hike I had a zipper on a sleeping bag malfunction potentially causing some serious sleeping discomfort in the single digit temps and a howling wind with a sleeping bag temp rating that was marginal for the hike to begin with. I decided to emergency shelter at the Muir Trail Hut as a result. When I got there two young female hikers offered me some safety pins to close my sleeping bag and keep me warm enough to weather out the night.
It's funny, when I offered her that safety pin bra fix I wasn't consciously thinking about safety pins being offered to me in that same place yrs earlier.
