Don: I have to mention, I really didn't like your sister's boyfriend.
Sally: Don't worry, neither do I! 
Don: I'm not sure what she sees in him. He's just obnoxious!
Sally: Well, I wouldn't put it that way, but he certainly isn't nice.
Don: Understatement!
Sally: He's not attractive either.
Don: True!
Sally: He's good to her and she seems to be madly in love. That's what matters.
Don: I guess, but I still don't get it.
Sally: Not up to us to get it, just so she's happy.
Don: True and we can limit our time with him!
Sally: But I like being with my sister. Guess we'll have to make it sister time!
Don: I like your sister too but he's a pan.
Sally: Yes, not sure what to say.
Don: Well, it's fine. I'll just grin and bear it!
Sally: Is it bear it or bare it? LOL!
Don: No idea! Google to the rescue!
Sally: LOL!
Don: Yep, grin and bear it, means put up with it.
Sally: Good to know!
Don: Wouldn't want to spell anything wrong on our text! LOL!
Sally: Anal to the nth degree! 
Don: LOL! True!
Don and Sally don't like Sally's sister's boyfriend, but she's happy with him, so they'll have to put up with him.
