Seriously, what gives people the right to tell me how to play? A few days ago I was at a party, and a load of the host's musician friends came round, guitars and all. They started messing about on their guitars for a while and then one of them asked me if I wanted to have a go. So I started playing my Shergold and began to play some random worship pieces. I got THREE notes in when one of the other guys starts getting all 'iffy' and arrogant to me. This is a rough conversation we had: Me: *gives count-in* (starts playing) Guy sshhhh you call that a bassline? Me: (sarcastically) Oh yeah, all three notes of it! Guy: Well you've OBVIOUSLY not that good if that's how you play! Me: OK smart*** tell me what I'm doing wrong! Guy: Well......*gives long list of trivial things* Me: Well what do you want me to play then? Guy: Whole Lotta Love by Led Zeppelin Me: I don't know any Zeppelin... We then got into a pathetic argument about how I should learn X Y and Z bassline and know this, that and the other, especially Zeppelin cause I listen to them. Eventually I just ended up storming off. This guy wasn't even helpful but just ended up ranting at me over daft stuff. How to deal with idiots like this?
