what if you did something fun and silly just the two of you? like bowling, indoor mini golf, laser tag, something random you wouldn't usually do? Is there a White Castle by you? You could do the fancy dinner they offer every Valentine's Day, which is hilarious and awesome!
my FI is going to be in Vegas with his brother ("visiting their parents" ) on Valentine's Day, so I'm looking forward to a nice quiet evening to myself, actually!!
(that may come off sarcastic, but I'm actually looking forward to some me-time, even if it falls on V-day LOL)
