Usually the blame is either on men or hormones.
when i was in college, for holidays we all went home by bus. A short 6 hr trip. since its holidays, buses are usually crowded. Sometimes, we got a good window seat to sit, sometimes just any seat, and many times, we stand for most part of the journey and go home. If we wait for a day or two, the buses will be less crowded and we can get good seats to sit and enjoy the trip. But we will loose valuable holidays that we can spend with our family - G.parents/Parents/Cousins. So, we never delayed. Its always travel thru rush hour. Why? because we knew we can enjoy later at our homes. The main purpose here is enjoying the vacations with our family.
The women/Men who wait till 30+ to find their best match are like the people who delay their trip to avoid rush hour, so that they can get less crowded buses with good window seat. They cut short the vacation to avoid a short discomfort.
For this delay, they will neither enjoy the trip nor the vacation. They will blame the others.
