Sad Realizations

so i have recently (though not very recently) come to two sad realizations:
1) i don't fit in with many people my age
2) i don't really have that many meaningful conversations anymore

i'll start with number one. as time has progressed, i continue to feel more and more as though i don't belong when i'm with people my age. now don't get me wrong, i have plently of fun and fit in with certain friends and get along well with many people my age, but with my age group as a whole i don't feel like i fit. i get along great with people older and younger than me, but for some reason which i've guessed at yet am not completely sure of, i don't quite like i'm in the right place when i'm surrounded by my peers. i have fun and get along with them, but i just feel like there's a gap in between me and them.

now for number two. this one suposedly isn't that uncommon for most people. according to one my friends, most people only have around 5 minutes of meaningful conversation a day. however, i feel like i used to have a lot more meaningful conversations with friends and just people in general than i do now. in fact, i'd say i even used to have more conversations that weren't even meaningful than i do now. once again, i can't exactly put my finger on a direct cause for this, but the fact of the matter is that i wish i talked to people (and that people would talk to me) more often about more than facts and something along the lines of "what's up?" followed by a "nothing much" (how lame and pointless is that exchange). more and more it seems like most conversations are about facts, plans, and pleasantries/formalities instead of two people legitimately having an interest in each others' lives and honestly wanting to hear what each other has to say.

i'll end with something kinda related (though not really) that someone told me that i think is very interesting and that i try to keep in my head:
You know you're in an argument when you're thinking of what to say next while the other person is still speaking. You're actually having a conversation when all you're doing is listening while the other person talks.
