Well Pug, I finally got tell my mum just this. Now, don't ask how she managed it, ah still can't get ma head to comprehend it. My mum, pushy as she is, insisted on rubbing cream that helps with dry skin on ma eyebrows this morning, right? Preferring to use her fingertips, instead of a cotton bud. Nearly poking my eyes out in the process, due to her long fingernails.
Well, I just suggest that she maybe cut them? Much to her annoying at such advice. Then later in the afternoon, she comes into ma bedroom to make my bed. Ah didnae want argue another argument, so I let her process. And in the middle of tucking the sheets in, she breaks off half the fingernail from her right index finger. Thankfully it wasn't serious or anything like that.
But, still, ah huv tae laugh at how often she dismissing my advice. While say I tend to be sensible one of the family.
