This is supposed to be about MY sins, though I'm growling right now about the asshole sitting next to me in the theatre yesterday...
I was a late cell owner, so I'd already made my Rules based on irritation with other people blabbing in lines at restaurants and grocery stores...
I don't yak to friends in public and I only take calls from my children when I'm with someone. I make sure there's not an emergency, speak very briefly and tell them I'll call back - but I'm sure purists would argue that I shouldn't even answer the phone. I can't help it. I'll answer my kids in every situation but a job interview or at work - and would make a quick call from work between classes, just to make sure kids are ok. (I guess I'm a nutty alarmist with my kids...)
I would never be on the phone while dealing with a service provider in public. I'd never cause my cell light to come on in a theatre, but yeah...if I heard the buzz - I'd check to see if it was one of the bairns... Checking involves a light - and I try to shield it, but who am I kidding: it's distracting. If I got more than one buzz in a movie, I'd walk out to check. When it is one of my children, mea culpa, I excuse myself with a "sorry" and walk out to return the call... I wouldn't engage in texting in a theatre like the friggin Bozo who sat next to me yesterday.
So, I suppose I'm not the BEST cell Neighbor...but not the worst, either. If it helps (and it may not), I'm cognizant of infractions and apologetic...
