<human>: Could you distill the essence of the text into 1-3 sentences?

This fuck up actually happened today.
So a little backstory: I am currently on America visiting my family and today I was headed to an aunts place who I was going to spend a couple of days with before I left this Sunday to my country. Anyways, woke up this morning and the person driving me is my cousin who is out on a work day, so when he gets out of home he can't go back until the end of the day (you can probably tell where this is headed). So I had my stuff packed up all ready to go, I say goodbye to my family,  make sure everything is set and we head off. As we're halfway to the train station where I'm being dropped off I get a call saying that I left my bag home. Yes I mean my luggage which I need for the flight in 2 days. So I end up going through a whole day at work with my cousin and his partner with nothing to do, not even internet.
<bot>: forgot the most important thing for my flight, had to go through a full day of doing nothing and left my aunt a very sad woman.
