这是对爸妈的孝心啊，连这点儿时间力气都不愿意花，枉费老爸老妈养你几十年。
zhè shì duì bàmā de xiàoxīn ā ，lián zhèdiǎnr shíjiān lìqi dōu bù yuànyì huā ，wǎngfèi lǎobà lǎomā yǎng nǐ jǐshínián 。
This shows your filial piety towards your parents. If you're not even willing to spend such a small amount of time and effort, it seems like mum and dad wasted several decades raising you.
