Hello,
What's more important: Trying to conform to some imaginary person's definition of what's proper or communicating your wishes and requesting those of the other person directly? Life is so short, what if you both want to spend time together and are just wasting time by not stating the obvious?
Back in high school, I had a friend who always gave me a ride home and often offered dinner. lol, once he realized that I was just refusing because I didn't want to impose, he said "Samuel, you're staying for supper and that's final!" instead of asking me if I wanted to stay for dinner in the future. heh He really had me figured out and because of that situation, I realized that sometimes people just really like spending time with another without any concern of making the frequency too high. I was raised to think that there was a natural limit to all social time spent with others, but in reality that limit is different for different people
Best of luck with your new friend,
Samuel
