Shavuot Lip Service
There are two times in the year when the convert goes into hiding: Parashat Yitro and Shavu'ot time. At these times, people begin all these nice dvrei Torah about how one should be nice to the convert, how many times its thus written in the Torah, a particular story about a convert, etc etc etc.
Its all very nice but don't ever let anyone know who's the convert! Otherwise the whole rest of the year they'd have to fiend off intrusive questions such as "why are you here?" "didn't you use to eat......" "shall I show you how to daven......" blah blah blah.
Don't get me wrong. I think any convert would give their eye tooth to be part of klal Yisrael its just that the lip service can be skipped. Either you treat the gerim respectfully, like any other Jew, or you think them strange and act thusly. But don't change because its shavu'ot or because you just finished reading Parashat Yitro and want to make yourself feel good.
For those who do treat the gerim respectfully, it is VERY appreciated. Everyone loves to feel welcomed and have a sense of belonging. Its a great and kind thing to do.
