Remember being madly in love, perhaps for the first time? You were "blinded by love," as the German idiom goes. In that state of mind, the object of your affection can do no wrong, and people tend not to notice faults, aggravating traits or problems on the horizon. The above German roadsign warns drivers to watch out for "lovestruck" frogs trying to cross on their way to spawn.

The German idiom has it that "loves goes through the stomach." In English, it's "The way to a man's (or woman's) heart is through his stomach." Delicious and lovingly prepared meals and confident cooking skills can win affections and maybe even make that special person fall in love with the cook. After all, eating a great meal releases endorphins, the so-called happy hormones.

First love, last love: The German idiom translates as, "Old love doesn't rust." It's a very old saying that stems from the Latin "vetus amor non sentit rubiginem" ("Old love does not know rust"). Feelings of love one had do not fade. Queen Elizabeth II and Prince Philipp, by the way, tied the knot in 1947.

All you need is love? The German phrase "live on air and love" describes the young couple without much of an income for whom air to breathe and love seems to be enough. A similar English idiom is more of a warning: You can't live on love alone, because, "Love doesn't pay the bills."

Beauty, money, power — why do people fall in love? Some couples look like a complete mismatch. The German idiom describing this situation is a bit ominous: where love falls ... A perfect example is the case of a swan named Petra on a lake in the city of Münster who fell in love with a huge swan-shaped plastic pedal boat.

"Lucky at cards, unlucky in love": If you win at cards, you won't have a happy love life — and vice versa, this saying implies. It seems to be an either/or situation. Perhaps people who are madly in love can't concentrate on gambling, so they lose.
