Men tend to do it to prevent from looking naive. Some guys will act as if they "know-it-all" to impress you rather than admitting that they could use some help with whatever that they are doing. Example: A guy I know started a podcast. I've been podcasting for over a decade. I know that the type of podcast that you wish to have and the frequency that you plan on doing it can determine what kind of setup you may need. When he told me his plan, I told him to reach out to me if he needed some insight or advice purchasing equipment. He told me that he had it figured out and did his research and knew exactly what he wanted to buy.
He spent almost $1300 for his podcasting equipment for something that fizzled out in less than a month. Then he asked me if I wanted to buy any of his equipment. I told him, "No. I'd never spend that much on equipment in the first place unless I was making my podcast a full-time job." His pride made him lie to me in the beginning when he said that he knew what he was doing when he didn't. And that was a very expensive lesson to him. I'm not saying that I'm an expert, but I do have experience, and sometimes two heads are better than one.
Women lie for pride's sake, but for different reasons. I once worked with a young lady who would participate in relationship discussions with us in the break room from time-to-time. She always bragged about how she is just "doing her" and isn't paying men any attention. She said that she was abstaining from sex and would make the next man wait because "she knew her worth". She was always the most vocal whenever we participated in the conversations. No man was ever going to get over on her!
Well, to this day, she doesn't know that I knew the guy that she was sleeping with at the time. Ms. Abstinence actually had a restraining order against her for stalking him and his girlfriend. He'd already bragged to me prior to my break room conversations with her that he'd slept with her a few times and she wouldn't leave him alone and she ultimately started harassing his woman.
All while she was telling us how she was "this and that" every day, dude was passing his phone around regularly showing nude pics of her. It made me feel badly for her to wonder how many people knew she was lying about how she "handles" men.
Look, we all lie. But it's more to it than doing so to get out of trouble these days. Social media tends to influence some of us to appear a certain way that we're not in real life. How many times has someone that you know very well posted something that you knew wasn't true? More than you can count?
Guys, it's okay to say, "I don't know" instead of acting like you know what you're doing and costing yourself time and money. Tell someone "I need your help" with something and learn to take instructions sometimes.
Ladies, you may want to reconsider some of the things you claim you do or don't do with guys because guys talk more than ever these days. There is no longer a code that guys live by. Don't have these guys fool you into thinking that they don't "kiss and tell" and have you looking stupid in these streets.
It's time for all of us to be adults and to stop lying.
