I've replied to people's comment before on purpose(like saying I agree or answering a question if the artist is someone who doesn't reply to stuff), but I don't think I've ever done it accidentally. 'Course, now I'm wondering....
yep, i've also come home, accidentally open the safe with 8 digit password, took some money, then accidentally got the car's keys, i accidentally jumped on it and drove around the city, finally accidentally used that money at several bars and clubs... all by accident. Does it happen to you too?
Sometimes when im on another profile and i leave a comment like : thank you for the comment/watch/fav and i see some stupid question like : what kind of tablet does he use...when its listed under his id...yes i do reply after all its a silly question, and when there is a random talk about something i add my thoughts lol but i think you mean it like: someone asked an artist something and you answered thinking it was a comment for you... and no this never happened to me before XD
The thing is... I use to call a friend "sister-in-law" because I "loved" her brother LoL.
Later, whan of the girls I watch submit a photo of her mother and then, for a strange reason I commented: "Oooh so finally I met my dear mother-in-law" And I didn't realise it until she commmented back with a very akward "ok o___OU"
I just felt soo embarrased at that time ;A; of course I explained her the confusion... But I don't think that she believed me XD.
