I have a papa who isn’t good at keeping a conversation going on LINE.

Papa: I went to eat ○○ today. Me: That looks delicious! Where is it? Papa: I’m going on a business trip tomorrow to eat ○○. I’d love to go on a trip with you next month. Me: Good luck with your business trip! I’d love to go on a trip too! When are you free next month? Papa: I’ve arrived for my business trip. It’s out of town, but there are lots of people here now that the state of emergency has ended. Take care too, ○-chan! ...So, as you can see, he completely ignores my questions and anything I say in response to his invitations, which is really frustrating. I really like this papa, but exchanges like this have been continuing lately, and I’m starting to get annoyed. Do you think it would be okay to casually bring it up next time?
