Da "feel
good" chemical dat your brain produces while you're interacting wif a nice
lady named
Sarah. (Can also be spelled "Saratonin", too, of course, if one or more of da Miss Smileysweets who's giving you companionship has an abbreviated" spelling of her name.)
If you make a point of diligently cultivating/maintaining friendships wif all of da sweetie-chicks in town named
Sarah and learning each of their
work/school/friends/family-time schedules, you will have a better
chance of being able to spend time wif at least one of dem at various times throughout da day (i.
e., if one
cutie usually has da mornings free, you can go visit her for a while after breakfast, and then
head over to another gal's house/workplace to spend her lunch-hour wif her, and then amble across town to hang out wif a third blinky-eyed damsel in da afternoon if dat's when she has time off), and so your overall mood during da day will be calmer and more stable because your brain will be able to produce Sarahtonin on a more regular basis.
