Cityville Valentine's Day achievements

I've been playing Cityville a lot later. Actually got badgered into it but now I'm hooked. Anyway, it's Valentine's Day and there are V-day related achievements with prizes.

The number of admirer's achievements is a no-brainer on how to get them. These are the other achievements that require you to receive a card from others.

Return to Sender - Receive a card with an Unhappy receiver

Tough Love - Receive a card with a Crab as object

Love Hurts - Receive a card with a Bomb as object

Feather Friends - Receive a card with Pigeons as sender, receiver and object

Food Fight - Receive a card with an Ice Cream and receiver avoiding the attack

Secret Admirer - Receive a card with Edgar as sender, Ruth as receiver and a Love Bear as object.

The secret admirer one was so hard to figure -.-"
