I had a great time hanging out with her and just spending time with her. I think she had fun, too. But when I brought it up the next day and thanked her she just said, "Oh, okay." It sounds cold, but I'm coming to the realization that it's just cultural. I wish she had said she had fun too, or that it was nice getting together. But all she said was, "Oh, okay." That's just the way it is. Talking to several of my Asian friends, they say that their moms are the same way. They show their love by doing things.
