Do you have parents that know nothing about most technology?
My dad is a total computer and technology nerd. He's a computer consultant or... something like that. Either way, he's really good with technology and can assemble computers together, but he doesn't know anything about social networking sites or whatever. He's completely clueless about that stuff.
On the other hand, my mom gets a headache whenever she walks into Best Buy. She's not that into computers or anything like that. I taught her how to send an e-mail, but she still wants me to help her with it. She can use her phone (and she can even set an alarm!), but she doesn't know how to text. At least she knows how to use Google and switch channels. She's also more familiar with social networking sites because she always watches the news. I also taught her many times how to send links through e-mail, but she forgot that pretty quick.
"Yeah, what's the link you want to send? This one? Okay, just Copy and... oh, to Copy, just right click... yes, Mom. You right click with the mouse. Yes, with that key. So Copy the URL... no, the URL is this right here. Think of it as an "address" for websites. So you Copy, that's right clicking, and Paste it on... right click, Mom. Right click!"
Do you get frustrated/annoyed with them when they try to act like they know what they're doing and ignore your advice?
Actually, my Mom just admits that she doesn't know much about technology and lets me do everything. I never get frustrated with teaching her. It's more of a "facepalm" moment.
