my client wants me 2 b more available but i don't care

so my work thing is that i’m a freelance graphic designer and i mostly just do jobs for this big company, which has been cool. they got me set up in their office here at home and i go there like once every two weeks or something. i mean, i can take calls from wherever, but most of the time it’s on my laptop while i watch netflix with no interruptions. perfect setup. but then this one manager lady, she keeps asking me if i want to work more regularly and come into their office all the time, like full-time. i just don’t understand why they need me there for meetings when i can be on calls and stuff? i love being at home and not having to dress up or commute every day. it’s great! she said that my client wants more access, but honestly, no one needs 24/7 support from a designer unless something is breaking and that never happens. if they can wait like an hour for me to reply, they will totally understand and i’ll still get the job done just fine. so yea, i’m not really planning on changing my setup at all. they should be happy with what works for both of us.
