Dont Send a Mind ta do a Heart's Job

I recently heard (or read i 4got) someone say "Don't send a mind ta do a heart's job and this got me thinking. We are taught since we are born to use common sense, think about what you do before you do it. So why would love be any different? To me that's y people get caught up, cuz they use their heart instead of their brain. The heart says "but I love him/her" when the brain says "he/she don't love u, u idiot, that's y he/she keeps f'n up, stop waisting ur time". Y do people use common sense in everything except love? It aint that complicated. that's how I feel @ least.
