I voted 'usually' but it's
kind of usually.
If I get up, say to grab a drink or something of course Princess is at my heels the whole time. More often than not, once she see's I'm sitting back down she runs to find a toy to play with, with me. So, yes she returns but not always to relax, to more or less take advantage of me trying to relax.
If were all snuggled with blankets & a movie or something she's more likely to chill after a disturbance & snuggle right back in.
