For many singletons, Valentine's Day falls somewhere between root canals and DMV visits on the likability scale. Luckily, we've come up with some activities that we guarantee are enjoyable any day of the week, whether you are single, dating, married or on your seventh divorce. Two are free. One involves black eyeliner. And another lets you scream as loud as you want. We heart you.

Public pillow fight

This free flashmob-style feather-buster has become a Bay Area tradition for thousands to let off steam -- and maybe even meet that special someone. Just grab your favorite pillow and head to Justin Herman Plaza at 5:30 p.m. on Valentine's Day. 1 Market St., San Francisco.

Picnic in the cemetery

Celebrate Valentine's Day like a goth with a picnic in the 226-acre Mountain View Cemetery in the hills of Oakland. The fountains, gardens and panoramic views are the perfect setting for a pensive dinner for one or stargazing with the crew. 5000 Piedmont Ave., Oakland.

A beer lover's valentine

Grab your buds for a fantastic three-course dinner with beer pairings and a gift to take home. We won't hold the Champagne and candlelight against those other guys. $30. Pyramid Alehouse, 1410 Locust St., Walnut Creek. www.opentable.com.

Secret Santa, valentine style

Who needs a valentine when you and your girlfriends have each other? Round them up, whip up some margaritas, and draw names from a hat so everyone gets a little gift. Then head out for some karaoke or watch chick flicks all night.

'80s power ballad sing-a-long

Raise your lighters in the air and join this mass karaoke tradition as you sing along to anti-valentine tunes by Guns N' Roses, REO Speedwagon, Warrant, Bon Jovi and Journey. Roxie Theater, 3117 16th St., San Francisco. $12 at the door. www.sfindie.com.
