I will mail my floss tag today, had everything ready to go on Monday and then it turned out that they had changed the insert of the mailbox to prevent fireworks from being thrown in. They had to replace this mailbox twice last year, so in a way I can understand it, but it's a little inconvenient. The only size enveloppes that fit now are the regular card sizes. Anything larger or thicker than that will have to be mailed elsewhere.
Anyway, I'll go to the central post office today to get it mailed out and hope it'll arrive soon.
