I have internet friends because I feel a responsibility to make everyone happy all the time and also because I like having people I can talk to about stuff that I won't have to face in real life in case a situation gets awkward
But if I were to lose a friend I'd just shrug it off and move on with my day
The only time I'd actually care about losing an internet friend is if they died bc I'd live with guilt that I couldn't do more for them and feel bad for anyone who knew them irl
