I crochet at home, alone and with Hubby. I crochet while watching TV if it's an easy pattern to memorize. The dogs are always nearby during crochet time. I crochet on long car trips, and on planes.
Sometimes I crochet in silence. Sometimes the TV is on, or I play my favorite music, or people are talking around me. I can't usually crochet and talk at the same time; I put my crochet down during conversations, unless it's a very simple stitch repetition.
I rarely have food or drink nearby while crocheting. I'm a klutz, and I don't want to ruin my work. Even without food or drink nearby, I have still gotten junk on a couple projects.
I crochet any time of the day, whenever I find a few spare minutes and the stitching bug bites. Most often, I crochet in the evening though.
