Tues. Feb. 13

 It's the day before Valentine's Day. So love is in the air everywhere, right? Does that include the animal kingdom? We're not sure what their holidays or rituals are - although we do know monkeys aren't particular about parnter or no partner if you catch our drift. (Astonished son to mum at the zoo: "Look, ma, look what the monkey's doing!" Mother: "Never you mind son.") So, on Tuesday Feb. 13 Jen Gresham, the Franklin Park Zoo's director of education, is giving a talk on the love lives of animals. Mating rituals, homosexuality, that thing the monkey was doing. Making this more fun: cocktails and light appetizers. Those things are free at the Back Bay Events Center, provided you pay $10 at the door. Goes from 5:30 to 8 p.m.
