I offered to wait with her until her brother arrived, but started looking at the tire and asking if she had a spare. She did, but it was flat! I used my compressor to reinflate it and started to change the tire. I felt like a total rookie using her jack! I kept thinking I was doing something wrong, but I couldn't figure it out. Finally got the car jacked up, and her old tire off, and just as I was putting her emergency spare on her brother arrived! He took over lowering the car and I finally saw what I was doing wrong with the jack. I was so embarrassed!
I said my goodbyes (nearly forgetting my compressor!), they said thanks and I was back on the road.
