I don't know exactly what your topic is focused around but maybe questions like
- How do you primarily communicate with others (verbally, face to face etc)
- What do you think the biggest changed in how we communicate is?
- Do you often use emojis to communicate over text and if so, do these make it easier to express certain emotions?
- Do you change the words you use when talking to different people? (more so how we say things or the videos we reference. If we quoted a vine the older generation wouldn't understand it)
These are just the ones i could think off the top of my head. I hoped they helped!
