Eh, we've all done it once or twice. I'm not really bothered by it. People just want to share a good thing and see someone else love a thing as much as they do. It's not bad. I'd actually feel kind of worse if I refused to watch a show a good friend recommended. If they know my tastes then I'd figure they'd recommend the show and if they didn't think it'd fit my tastes then they don't.
Now if that friend for some reason really wants you to watch some horrible bullshit? Then yeah, I get it. I'd usually just recommend a friend watch a cool thing like JoJo then leave it at that because I don't want to say anything more. Some people take more convincing than one sentence though so my style of recommendation doesn't exactly work for all people.
I went to mail some things and get gas. My fingers hurt a lot due to the cold winds so I took like 3 minutes to turn the gas nozzley thing on my car. I then accidentally sealed something I didn't mean to inside a envelope at a post office so I ripped it open, threw it in the garbage, and then got a different envelope. I was slightly scared someone would call me out and say I need to pay for the envelope I used.
