im bad at social interaction because i cant really do small talk. if i dont know the person or their interests, and especially if i dont want to make friends with them in the first place, then my mind goes blank and i have no words to say. even if i want to talk, sometimes i just cant. im not talkative in the first place but rarely the mood strikes me just right and i can socialize like a normal person, but its VERY easy to snap me out of it and retreat into my shell.
i remember one time i was in such a mood with family and i was talking and making jokes, and my mom gave me a little bit of shit over finally talking to the family. shut me right down and all the anxiety came rushing back. my sister even got upset with her over giving me shit over finally opening up.
old people just have no tact.
the person you were replying to is definitely an asshole though
