"Head home before asking a sim that you've met downtown out on a date.  If you ask them over the phone, you'll have a better chance of getting a yes because hygiene and other negative physical factors won't work against you." - TEM

"if in the morning your sims moods are low and you cant be bothered to spend loads of time getting them better just hold down ctrl shift and c until a box will appear int the top left hand corner in this box type in 'move_objects on' the click on buy mode and delete your sim then when you click back on live mode click on your sims face on the picture at the bottom on the blue thing then when your sim reappears his/her mood will be great all ready for a nice time flirting downtown." - kate

"Buy a magazine downtown if you want to change your Sim's interests.  For example, reading The Avarix will skew your Sims' interests towards money, politics, and technology." - TEM

"The best way to meet new people is to greet them on the street.  Check for compatible interests (use "What Are You In To?") to identify dating prospects before you spend a dime." - Kaibob
