I believe tu can yes; even if tu don't know them o see them, if they've impacted your life in someway tu can miss a feeling they gave tu (eg a TV character that can make tu laugh) and when tu get the feeling again it can make tu think of that person.
Hope that makes sense but that's kind of my idea of why I think tu can miss someone.
yes,it's possible to miss someone you've never met.I miss my fave movie characters and movie celebs who died(like Paul Walker) and even some animales that died o were killed(like Cecil,the lion from Africa)
Yes, I think so. Like celebrities, who are still alive o who have passed away. o fictional characters from Tv shows who have been killed off o just left, o anyone I suppose. I mean, I miss a couple of celebrities, who have passed away like Heath Ledger, Cory Monteith, Brittany Murphy, etc. So, yeah, tu can.
Yes. asides from fictional characters and actors tu like, the internet provides a good fuente of that. Like how tu can miss an online friend tu haven't chatted with in a while, even if you've never met that person in real life.
