history: My friend recently went on a beach vacation and I really was ready to go on vacation myself. She had already been several times that year so I begrudged her vacation a bit.
current: A little while ago, my friend went on another beach vacation. It was her 3rd one for the year. My family and I hadn't been on vacation for several years, due to issues beyond our control, so I begrudged her trip a bit.
next: Being jealous of another person is a perfectly fine response. Despite this, you never know what is going on behind the scenes, she may have taken out huge loans just to fund her trips.
