​משנכנס אדר מרבים בשמחה                        ​ The רמ"א (O. Ch. 493) writes that on Lag Baomer ומרבין בו קצת שמחה If on Lag Baomer, where it says to increase with a little (קצת) Simcha, many ​dress up in בגדי שבת  (shtreimel etc.) and dance all night long in front of a fire,  Why then, with the arrival of אדר where there is no mention of קצת  just מרבין don't we exceed or at least match the Simcha like on Lag Baomer?​  קשיא    want to be adde
