Why dating can be compared to a can of Pringles
If an alien came down to Earth today and asked about modern dating, I'd tell them it's like a can of Pringles.
(Can? Tube? Whatever.)
You don't even need Pringles
There are so many other brands on the shelf (i.e. there are so many other options than dating, such as don't date for one) and you tell yourself you'll pick something different, convincing yourself you don't need the Pringles—which in modern dating terms, means you'll convince yourself that those Instagram/Pinterest mantras about how being single is actually pretty great, are actually pretty accurate.
There are so many different flavours
You're spoiled for choice when it comes to Pringles, so in simple terms, you're spoiled for choice when it comes to dating. There are so many choices out there, original (i.e. the cute, dependable type of person everyone should go for), salt and vinegar (i.e. also cute, with some added extra you figure out is either good or bad) then there's roast chicken and herb (i.e. the person you're interested in figuring out, but you know they're trouble).
You can't resist
You tell yourself you don't want Pringles (i.e. you don't want to put yourself through dating, and all its hardships) but you can't resist all the good parts of dating—how good it feels to go out, to get to know someone and enjoy their company...only for it to fizzle out.
