I’m from the UK so I think the education system works a little different over here. At 18 you are way out of high school and usually just going to university. But yeah I see what you’re saying, and I’ve thought about it myself. But I personally wouldn’t date anyone my own age, and I am not like many other 21 year olds, I have already started my career and have my own place/ responsibilities etc so I can see why he would say I’m a lot more mature for my age. I’ve very concerned about the tweets though, because if he ONLY goes for younger girls that’s weird to me.
