Have wewe ever had this feeling toward someone when wewe can't wait to see him/her and when wewe do it's like every part of your body shakes and wewe feel your losing your breath, your moyo beats like crazy and wewe suddenly feel so hot, every cell of your body calls that persons name, and wewe feel like you're ready to do anything that person asks wewe to do .. you'd even sacrifice your life for him/her, when that person becomes the reason why you're alive, and wewe think of him/her before every action, and nothing would make wewe happy zaidi than seeing that person happy
That's called upendo .. and tell wewe what, I've never fell in upendo :3
