I'm reading a book on lubricants...

Usually I'm an avid reader, but I found that one hard to pick up.

smooth.

I meant to read the same book, but it slipped my mind

I found that the author glossed over a lot of stuff.

I tried doing this once. I couldn't retain anything.

Turns out lubricants are often neurotoxic. The more you know....

I found the concept hard to get a grip on

i was confused until i searched it up and realized that father's day is in june in most countries (here it is in august)

wikipedia: Father's Day

Crazy fric...
