Online I (almost) become extraverted. I'm more 'aggressive', blunt. I share my emotions and my thoughts. In some way I feel like I can connect more with people online, but at the same time I feel like they are not 'real'.
Also because it takes time for me to put things into words. IRL, I tend to forget stuff. Later on I'll be like 'fuck, I forgot to tell them this or that' and it annoys me, even though it's not even that important.
IRL I'm more reserved. But with the right people I can be playful, just joking around like I do on the internet.
I'm active on another (Dutch) forum too and I miss the interaction I had four/six years ago on another forum. The people there are more stiff, there isn't a lot of 'playful' and direct interaction (except for discussions, I think many people there hate me :')). When I was 13-17 I spend much time on a certain forum. I even bought a game because the people there played it. It really felt like a friendship, a close community. I don't think about it a lot but now I am thinking about it... I took it for granted, I didn't realize what I had back then (but that's a human thing I guess). A community, some sort of 'friends'. I spend a lot of time with them.
I hope I can ever find something like that again.
So IRL I'm more introverted. I always think what I can say, but I almost never speak. I don't know why. I'm fine, just thinking. Though I should think about the fact that people like it when you say something too. I suck at being productive IRL. Online I feel like I actually do something.
What's the same for me in IRL and online, I'll idealize people. On the first forum I joined I thought some people were very interesting. I would 'accidentally' post in the same topics they posted, 'like' the same bands/groups/people they liked even though I didn't know the band etc. I would interact with them when I could.
Another thing is that I don't add friends first online, I'll always wait for the other person to do so. IRL it's just the same. I am unsure if I can consider someone my friend unless I hear them say that they consider me a friend. Then, when talking about them to other people I will (most of the time) refer to them as a 'friend'. It's probably because deep down I am still insecure, I wouldn't want to add someone as a friend, or refer someone as a friend with the risk that they don't feel the same or think something like "What does that b**** think she is to add me as a friend".
