I just forgot my freakin' debit card in the ATM for the 3rd time in the 5 years I've had it. I do the transaction, press "No" for more transactions, and merrily go on my way leaving the card in there. Luckily no one came immediately after to claim it and the machine sucked it back in to be shipped to the main branch.
There have also been many times when I've gotten groceries, paid for them, and walked away, forgetting to bring them with me. The clerk has to tell me I forgot them.
Now, I can always remember a list of groceries and can tell you pretty accurately how a conversation went.
So, tell about your experiences and maybe relate it to MBTI as well.
