cela ne me surprendrait pas du tout si I wouldn't be in the least surprised if; I wouldn't be a bit surprised if; I wouldn't be at all surprised if
d'après moi in my view
en ce qui me concerne personally speaking; personally; as far as I'm concerned
je ne serais pas du tout surpris si I wouldn't be at all surprised if; I wouldn't be in the least surprised if; I wouldn't be a bit surprised if
je ne serais pas le moins du monde étonné si I wouldn't be a bit surprised if; I wouldn't be at all surprised if; I wouldn't be in the least surprised if
je ne suis pas surpris que I'm not surprised that; no wonder that
