No. I'm a pretty understanding person, and when you're pretty good at understanding why some people do some things (or at least if you're interested in trying to understand), there's not really much that others do that seems irritating.
I think one of the biggest problems in interpersonal relations can be that a lot of people who find others irritating either can't or won't try to understand what someone else is going through. A lot of people THINK they know what motivates someone when it comes to the actions or words of someone else; but if they understood the other person as much as they think they do, they wouldn't be irritated; because most of the time they'd see what the other person does as (of course) "understandable".
I like people, and I don't ever want to be someone who sees others as "less" than me, and that's essentially what people do when they see others "pesky and irritating". If someone else is being happy I'm happy for them. If someone else is not happy, I just kind of understand that people can't always be happy; or else I secretly remind myself that I'm thankful I'm not as unhappy as they are. Sometimes someone who can't stand "whining" is someone who, himself, has so many problems he can't deal with having anyone else throw his own into the mix. That's understandable too, but I don't think one person's feeling like he's reached his saturation point with negative stuff should think less of the other person, who doesn't realize that or who needs to express himself to someone he's close to. A lot of people in this world have a lot of struggles and problems. I don't think it's fair or reasonable to expect them to keep it to themselves because we don't feel like listening, or because we've decided how long we're willing to approve of their talking about the negative stuff before we decide they should be quiet. I've got the energy to be supportive of someone else, but I've also got the sense to know when I need a little break from them (even if I don't allow myself to feel irritated by them).
I think we're happier in this world when we respect and try to understand others. Looking down on them by seeing them as irritating may allow for a temporarily inflated ego, but it separates us from other people and prevents us from understanding them, and ourselves better. Life's just happier when you give most people a break and the benefit of doubt when it comes to why they do something you might tend to see as irritating. Pretty much the only things someone else does that aggravates me are a) being nasty, b) being aggressive, c) being malicious, and d) assuming/imagining the worst about other people's motivations, and then disliking the other person for what they imagine.
