The husband apologizes for his nose scratching and apologizes for not using tissues. The wife reminds him to carry hand sanitizer and reminds him to use tissues instead of licking his noses.

*scratches nose* Sorry, my nose was itching. 
gpt
Ew, did you just lick it in public? That's not very hygienic. 
human
You're right. I should have used a tissue. 
gpt
I mean, it's not like we're in the middle of a pandemic or anything. 
human
I know, I'm sorry. I wasn't thinking. 
gpt
Remember when we were at that wedding last year and the groom kept picking his nose during the ceremony? 
human
Oh yeah, that was gross. 
gpt
And then he shook our hands during the reception. Ugh. 
human
I'm glad we always carry hand sanitizer with us. 
gpt
Yes, that's one good habit we have! But let's remember to use tissues or wash our hands instead of licking our noses from now on, okay? 
human
Agreed. Lesson learned.
