I'm going to lie about whether or not I've seen memes that my girlfriend sends me
Why would you lie about that to your girlfriend?
I have good reasons for that. I want to look smarter than my friends and be in-the-know.
You shouldn't lie to your gf, even about memes. You should be honest if you saw them or not so she knows.
I'm trying to look like a cool girlfriend, instead of boring.
I don't think lying to your partner makes you look very cool. You should just be honest with her, it's not that big of a deal.
