Love is
waiting for someone to finish her overtime work, even if it means waiting for 12 hours and helping her out a little in the process, and bringing her home despite your exhaustion.
Inversely, love is not waiting for someone and instead telling him "Tara! :) Alis na tayo ng office." ("Come on! Let's leave the office.") to get to spend as much time as possible together before you leave for another activity.
