If I could only choose a few close friends, it would be very difficult for me to choose. I would choose people I have known for a long time. I would definitely choose people who I can always trust, who will support me and help me. of course I would also help them and support them.
I think I would be close friends with people I know in person and not just chat with them online. Back in the day, people couldn't meet online, which is why I think they had fewer close friends.
Nowadays everyone knows everyone thanks to the internet. I think it's easier to get to know each other because of this. however, the downside of online talking is that we may not be able to trust the other person in the same way as a person we know in real life.
