I dislike introverts who need to be told everything multiple times when in a group setting. You have to keep offering them food, try hard to engage them and check on them to ensure they are ok. They will just sit quietly in a corner and you will never know if they are ok or not, or if they are upset or need care. I hate doing that labour for them.
Like dude you can talk, you are normal! You are an adult, not a child. Please emote, talk and let others know what you want or don't want. Be a part of what's going on and don't kill the vibe by just disconnecting with who's around you.
Sincerely, an extrovert who always puts that effort.
