My love/hate with the Hanko is simply that with all the pain to memorize the Kanji in your ever changing address, job address and future addresses for filling out forms... it's just an extra kick in the stomach to be filling out forms somewhere only to not be able to complete them because... *I forgot my hanko.*

I won't deny that it's 100% my fault, but it's just a day killer of a feeling to know I have to go back home and get it and hopefully come back before whatever business I need it at closes.
