Go to Yokohama to attend a wedding party

I don’t go. My husband is going there alone this weekend.
He seems to forget all things, getting a ticket, sending his shirt to the laundry, buying an envelope for presenting a gift of money, and withdrawing some money (it should be new bills!)
I have sent his shirt to the laundry for the moment, and.. I think I need to press his trousers? But he has not decide which to wear.
He doesn’t do things until the last minute. Always procrastinate!
