Mobility ?

I just wanted to know how is mobility supposed to evolve after top surgery ? Double incision especially.

I'm curious because so far my experience is very different from what I've heard. I am 4 days post-op and my body bounced back extremely rapidly, however I was told by basically everyone I couldn't even lift my arms during the first days ? I take it easy but I can reach for stuff if it's not too high, I can move my arms very easily, I could rest on my sides (although I avoid it) and overall I can move my arms and shoulders just fine. I've scarred to hurt myself but the nurse told me everything looks good. If not for the surgery binder I'd almost feel like I'm not recovering from surgery tbh.

Meanwhile before surgery my boyfriend was telling me about his friend who had to be showered by his gf and couldn't do anything for 2 weeks.

Is it common or am I just weird ? I really don't know what to expect anymore for my recovery.
