Saturday < Sunday

Earlier this November, there was an Event held in Jakarta, which is Indocomptech. It was an IT and Digital Lifestyle Show, basically an IT exhibition. There was something that I wanted to see and may have took my interested, and I might have bought it while I'm there. Because, it was my first time to visit this kind of event. 2 Weeks before the event held, I asked my mom to accompany me there. She said she might have gone with me, but  she said it depends. So, on the day before the event, which is Friday, I remind my mom again, and she said okay. On Saturday however, when I was about to leave, my mom asked me where I want to go. I was really shock because she didn't remember that she would accompany me, and it turns out, she also got something to do in the afternoon. I think that she must have thought the event was on Sunday. I could have gone there all by myself, but I don't think that my money would be enough for the trip and for shopping at the same time.
