Question 1 I think is packaged in your follow-up questions:
- Did you not miss them?
'Missing' someone is an interesting way of thinking about it. When should you 'start' missing someone? I find that often I miss people intensely soon after we meet. This can be difficult, because it may not be possible or practical to meet or communicate with someone immediately, but then that 'missing' starts to wane. By the time it starts to become stronger again, a significant period of time might have passed.
- If you did, why didn't you contact them?
Missing someone is fairly subjective as mentioned above, but for me, contact alone is not enough to stop me missing someone. Meeting in person is. If I contact someone, it does not stop me missing them we are unable to meet in person, and in fact in some cases, makes me miss them more. Many of my friends don't live in the same city (or even the same country) as me.
- If you didn't, why do you care?
Because friendships take work, like any other type of human relationship. Someone who currently is an 'acquaintance', who I wouldn't really be too upset about not seeing frequently could develop into a friend.
> 'One can not forget about friends, one can only stop caring.' - I think here you're using a very literal definition of forgetting. I think most people don't actually forget about friends, they just use the word forget as a shorthand for 'not actively thinking about all the time'.
