Tip one: don’t trust your friends with the keys to your apartment; one day they might let a tenant in without your knowledge. Tip two: when love knocks on the door, don’t rush to lock the locks and hang up a sign “No one is home!” It’s better to invite your guest for a cup of tea, otherwise you risk being left without a door. Tip three: if you violated both first tips, don’t complain about fate, but blame yourself! When luck takes a vacation, it’s time to pack your suitcase and set off in pursuit!
