However, Dr. Hong cautions the excited couple that things may not be exactly the same as they remember.

"Just be aware that it might feel a little different than it did before," Dr. Hong explains. "Where as before, it may have felt like the closed handshake of a closed business deal, now it may feel more like the mandatory handshake of an 8-year-old at his parents' dinner party."
