My S22 called last night and we had the most hilariously awkward conversation.
To give backstory - I shop at a grocery store where, for every $100 you spend you get 10 cents per gallon off gas. So whenever I build up a lot of money, we take both cars to fill up at once. I drive the lead car, my husband pulls up right behind me, he fills up the tank, stands there holding the nozzle, I move both cars up so that he can now fill the second tank. It’s a huge PITA, but last night I had $1.20 off per gallon, so it’s worth it to stretch that across both cars.
So husband called me to say he was on his way to the gas station and I needed to leave the house then to meet him there. As I’m walking down the stairs S22 calls me for his weekly check in. I’m trying to talk to him while putting on shoes, coat, getting keys etc. I get in the car and the phone transfers to the car ok. We talk for a few minutes before I get to the gas station, where I see husband already waiting. I drive past husband to pull up at the pump and all of a sudden, S22 is GONE.
As I drove past the other car, my phone transferred to that car. I realized what happened, so picked up the phone to try and bring him back, which took a second. Then I get him and he’s all, “I don’t know what happened, I was talking to you, and then all of a sudden there was some man singing”. Apparently when he busted in on husband’s car, husband was in the middle of singing along with Livin’ on a Prayer. 
So I’m trying to explain to S22 what happened, while also kind of dying laughing, while I pull up to the pump and husband pulls close behind me, and it happens AGAIN. To try to fix it, husband doesn’t hit the button to transfer the call back to the phone, instead he just disconnects, which hangs up the call on every device.
So then I get out of the car to get the gas started and S22 calls me back with a vaguely annoyed tone of “what is even happening here” and at this point I just can’t stop laughing at all of them.
I eventually just told him I’d better go because there was too much going on at the gas station. I texted him later to apologize for all of the hullabaloo/
I’m a little frustrated, because he really was talking and sharing stuff, and lately he hasn’t had much to say on the phone, and here he was trying to impart information and I couldn’t follow the thread of the conversation as it kept bopping between devices and my poor concentration.
But what I think I heard was: He’s got a final project done for one class; for a second class there appears to be a project for this week, but the professor hasn’t assigned it yet so he was going to talk to him today; for his year long capstone project/class he’s pretty frustrated with how the research is going and the snags they are running into; he’s in charge of new member education for his fraternity and it’s taking a lot of time, but it’s about what he expected; he’s kind of stressed out with all of that and the extra time it’s taking to job hunt and he really really needs his winter break.
