It’s my first time meeting my sister’s boyfriend and she talks casually to me

(1)It’s not good to talk informally when it’s our first time
(2)I feel bad even if I’m 31 or 21 years old

(1)If the age gap is like that, I think it’s okay even if I’m in a good mood
(2)as if it were going to go by
(3)Hey! Get some water!!! It’s not like this. You have to squeak
(4)Hi! It’s probably like this
(5)55. Too sensitive

(1)My sister’s boyfriend is because my sister is a little young
(2)You spoke formally to her for the first time 5 days ago even though you’re 20 years apart

(1)You’re being rude. You’re being sensitive. No, no
(2)I’m not sensitive at all
(3)But no matter how young the other person is
(4)I wonder what it is to speak informally
(5)If you go to college or work, you’ll all know

(1)I’m going to let it slide
(2)If you think it’s for friendliness
(3)I don’t like it. But the t-shirt
(4)If you gave me pocket money while talking informally, I’ll admit it

(1)I don’t like it when someone I don’t know talked down to me because I’m old, but I said, “Friendly words.”
(2)Since it’s “Your boyfriend”, if you really spoke casually because you were like a younger brother, I’m happy
(3)Since I’m your girlfriend’s
(4)33 If you’re OOO’s younger brother, it’s OOO

(1)Even if it’s your real sister’s boyfriend, if it’s your first time, it’s honorific

(1)I don’t think much about it. If it’s your sister’s boyfriend, it’s too friendly
(2)I think so. So I’m a bit reckless
(3)If it’s your boyfriend, I don’t have any thoughts
(4)It’s polite to use honorifics for the first time, but only my boyfriend who’s 6 years younger than me
(5)If it comes out, I’ll talk informally without realizing it

(1)I don’t like talking informally when I first met him
(2)I think it’s different depending on how you speak without honorifics
(3)No matter what the relationship is, I don’t really like talking informally when I first met him, but his first impression wasn’t that great. Maybe it’s because he wants to get close quickly, but it’s hard to judge based on his first impressionThat’s why we have to move on
