Some advice to make your life a little easier…
… don’t expect gifts. If they happen, then great – you’ve gotten a bonus. But don’t expect them as if you’re entitled to them.
You’re not entitled to a chosson Shas – even if it’s “standard.”
And besides, what are you going to do if you don’t get it? Break up with the girl? Potentially ruin your sholom bayis over the next few decades by nursing a grudge against your in-laws for not giving you a Shas?
Just let it go. If you get one, great. If not, just start saving to get yourself one in the future.
