Well, it may be a major one, but not necessarily a "one-of-a-kind" because I have done that too many times to count!! At the time, I think that I am making it easier on myself to leave some clothing in the suitcase. But, within the next hour, I've forgotten that they are there and I put the suitcase away and then spend the next couple of weeks (or sometimes months) looking for (and giving up as lost) those items of clothing.
Sometimes, I buy replacement clothing, only to open the suitcase, when packing for our next trip, to find everything that I thought I had lost. So, welcome to my world rofl
Peace and Blessings
