What's a good app for getting a ride or ordering dinner when I'm visiting my daughter in the city? Something easy to use, even for an old-timer like me.

My daughter, bless her heart, suggested I try Grab when I visited her last month. She said it's the best way to get around and order food in the city without having to hail a cab or call in an order. And you know what? She was right. It took me a few days to figure out all the features – why do they hide the settings button there? – but once you get the hang of it, it's surprisingly intuitive. I used it to get a ride to the theater and then ordered some Thai food for delivery when we got back to her apartment. It's like having a teaching assistant in your pocket, handling all the logistics. My students showed me this trick for setting up your payment info beforehand, which made things even smoother. I was impressed. Makes city visits a whole lot less stressful for this small-town teacher.
