Hey, sorry but my 3DS is having issues right now (keep getting the 018-0512 error) so I don't think I can pick up Olivia, so you can give her to someone else. Sorry
You can bring Katie over to my town if you still have her. I dropped her off at another town earlier today, so she'll probably end up dropping her ticket on the way. You'll still get a letter with a gift tomorrow, though.
