I think if you reread your post you might understand where they are coming from. You capitalized IS and IS twice which does read kind of snarky. Now, I know you didn't mean it that way because I've read tons of your posts before, but the OP is relatively new on here and maybe didn't read through your tone.
I'm just pointing it out and in no way want to argue about it. It's just the context of written compared to verbal. Geeze, now I'm second guessing what I'm writing because I kind of sound like the grammar police and that's one of my biggest pet peeves on the boards
I think the best response was have fun waiting in line, because I'd much rather be there than where I'm sitting right now at work...
Have fun!!!
