My "Duh" moment in my first day of nursing school clinical

Well, you guys know you just wanna puke the first day of clinical. I was lucky enough (note sarcasm) to have Nurse Ratchet for my sub-assigned nurse that day. (An unfortunately unhappy person who takes it out on everyone else). I asked her if she needed any help, and she told me to go get ice for her pts in the "white bags". I asked the CNA where I could find them and she showed me and I filled them up. I brought them back out to my nurse and she snapped at me, "That's not what I asked you for. The WHITE bags." Guys, these bags sure as anything were white because I had gotten her ICE PACKS for all her pts rather than ice bags for the pts' ice pitchers! What she should've asked me for were the CLEAR bags of ice . . . but anyways. I cried that day, but I can laugh about it now!
