Or it may be exactly what a companion intends: to let it be known that she has availability that day. There are some who are fixated on speculating on whether one escort or another is

Another fun fact that some super poster hobbyists fail to understand is that it's not always about them. There are so many sweet as pie gents who are introverted/low-key and like to read the coed posts made by different providers to get a feel for their personalities and interests before booking even if they choose to abstain for posting.
...and it's probably not what the posters intended
